Classification of Polynomials

Image
Today new experience is..., Polynomial is being categorized according to the number of terms and the degree present. Polynomial equations are the equation that contains monomial, binomial, trinomial and also the higher order polynomial. The form of a monomial is an expression is   where n is a non-negative integer. The variable ‘a’ is called as the coefficient of   and n is the degree of the monomial. Based on the value, one term is called as monomial (when n = 1), two-degree polynomial (when n = 2) and three-degree polynomial (when n = 3). Example : The polynomial is classified by the number of terms as: Monomial – One term – 3x Binomial – Two Term – 7a-5 Trinomial – Three Term – 

Railway time and ordinary time

Image
Railway time  was the standardised time arrangement first applied by the  Great Western Railway  in England in November 1840, the first recorded occasion when different  local mean times  were synchronised and a single  standard time  applied. Railway time was progressively taken up by all railway companies in Great Britain over the following two to three years. The schedules by which trains were organised and the time  station clocks  displayed were brought in line with the local mean time for London or "London Time", the time set at  Greenwich  by the  Royal Observatory , which was already widely known as  Greenwich Mean Time  (GMT). Ordinary Time  comprises two periods of time in the  Christian   liturgical year  that are found in the calendar of the ordinary form of the  Roman Rite  of the  Catholic Church , as well as some other churches of  Western Christianity , including those that use the  Revised Common Lectionary :  the  Anglican Communion ,  Methodist churches

Rhombus

Image
Properties of Rhombus : Opposite sides are parallel. 2 Opposites angles are equal. Adjacent angles are supplementary. All the four sides are equal. Diagonals bisect each other at right angles. Vertices are  not 90 ∘ It’s not a cyclic quadrilateral.

parallel lines

Image
Parallel Lines Lines that lie in the same plane and do not meet one another are said to be  parallel lines . In the accompanying diagram, the line  AB  is parallel to the line  CD .  This is indicated by the similar arrows. Drawing Parallel Lines A ruler and  set square  can be used to draw  parallel lines  as described below. Step 1:   Position an edge of the set square against a ruler and draw a line along one of the other edges. Step 2:   Slide the set square into a new position while keeping the ruler fixed exactly at the same position. Step 3:   Draw a line along the same edge that was used in Step 1.

Types of quadrilateral

Every closed figure has a definite shape. The shape of an object depends on the number of sides and angles constituting it. Now, depending on the measurement of lengths of sides and degree of angles, varying shapes can be formed. One such shape is a quadrilateral Quadrilaterals and Types of Quadrilaterals Quad means four and lateral means sides. All closed figures with four sides are called quadrilaterals. The sides of the quadrilateral may be equal, unequal, parallel or irregular which forms the basis of varying shapes in these four-sided shapes. Whatever may be the external shape, every quadrilateral has four sides, four vertices and with all its angles adding up to be 360 °. The various types of quadrilaterals are     1.Parallelogram, 2.Rectangle, 3.Square , 4.Rhombus, 5.Trapezium

Tables for Metric Measuring

Linear Measure 10 millimeters (mm) = 1 centimeter (cm) 10 centimeters = 1 decimeter (dm) = 100 millimeters 10 decimeters = 1 meter (m) = 1,000 millimeters 10 meters = 1 dekameter (dam) 10 dekameters = 1 hectometer (hm) = 100 meters 10 hectometers = 1 kilometer (km) = 1,000 meters Area Measure 100 square millimeters (mm 2 ) = 1 sq centimeter (cm 2 ) 10,000 square centimeters = 1 sq meter (m 2 ) = 1,000,000 sq millimeters 100 square meters = 1 are (a) 100 ares = 1 hectare (ha) = 10,000 sq meters 100 hectares = 1 sq kilometer (km 2 ) = 1,000,000 sq meters Volume Measure 10 milliliters (ml) = 1 centiliter (cl) 10 centiliters = 1 deciliter (dl) = 100 milliliters 10 deciliters = 1 liter (l) = 1,000 milliliters 10 liters = 1 dekaliter (dal) 10 dekaliters = 1 hectoliter (hl) = 100 liters 10 hectoliters = 1 kiloliter (kl) = 1,000 liters Cubic Measure 1,000 cubic millimeters (mm 3 ) = 1 cu centimeter (cm 3 ) 1,000 cubic centimeters = 1 cu decimeter (dm

Constructing a perpendicular line

Image
After doing this Your work should look like this   Start with a line and point R which is not on that line. Step 1 Place the compasses on the given external point R. Step 2 Set the compasses' width to a approximately 50% more than the distance to the line. The exact width does not matter. Step 3 Draw an arc across the line on each side of R, making sure not to adjust the compasses' width in between. Label these points P and Q Step 4 At this point, you can adjust the compasses' width. Recommended: leave it as is. From each point P,Q, draw an arc below the line so that the arcs cross. Step 5 Place a straightedge between R and the point where the arcs intersect. Draw the perpendicular line from R to the line, or beyond if you wish. Step 6 Done. This line is perpendicular to the first line and passes through the point R. It also bisects the segment PQ (divides it into two equal parts)

Measures of time

Image
A new measurements post! In this case we are going to talk about time measurement. How can we measure time ? What units are used? The tool used to measure time is the clock. The unit that we use as a reference is the day. Regarding the day, there are units of time that are smaller than the day, and there are other units of time that are greater than the day. Units Smaller Than The Day: A  day  has  24 hours. One  hour  has  60 minutes . A  minute  has  60 seconds . Units Larger Than The Day: 7 days  are one  week. Between 28 and 31 days  are one  month. 12 months  form one  year. 10 years  form a  decade. 100 years  form a  century. There are many more units used to  measure time , but these are the most common. How can we change from one unit of time to another?  In the next picture you can see that to go from hours to minutes or to change from minutes to seconds, you must multiply by 60. On the other hand, to change from seconds to minutes or from minutes to hours,

MEASUREMENTS

Image
METRIC SYSTEM OF MEASUREMENT: The metric system is a  system of measuring . It has three main units: m   the  metre  for length kg   the  kilogram  for mass s   the  second  for time With those three simple measurements we can measure  nearly everything  in the world! Examples: Metre The  length  of this guitar is about  1 metre :   When unfolded this ruler measures  2 metres :       Kilogram This gold bar has a mass  of  1 kilogram . A dictionary also has a mass of about  1 kilogram . Second 1 second  is about as long as it takes to say  "one thousand and one"   Larger or Smaller But what if we want to talk about really big or really small things? Answer: we can use  Metric Number Prefixes like "kilo" (a thousand) and "milli" (one thousandth) and so on Examples: something that is 1,000 metres is a " kilo metre" a very short time of  one thousandth  of a second is a " milli second" In

Today experience

Today I am going to 1st hour in the class 7th standard I teach the exercise problems in that chapter was meas urement and then Iam to going to 10th standard I write the sum using  blackboard after I teach the sums and then I am going to 6th standard I teach the topic appli cation of HCF and LCM.And then celebrate the saraswati pooja in my school.

Today my class

Today 1st hour Iam going to 7th standard I teach the topic was measurement and then concept was how to find perimeter and area with the help of formulas I teach the example and exercise problems.After I am going to 10th standard I write the sums and then teach the exercise problem.And then I am going to 6th std I teach how to find the HCF(Highest common factor) and then how to find the L CM(least common mul tiple) explain with the help of blackboard.

Perimeter

Image
A  perimeter  is a path that surrounds a  two-dimensional   shape . The term may be used either for the path itself or its  length —it can be thought of as the length of the outline of a shape. The perimeter of a  circle  or  ellipse  is called its  circumference Perimeter is the distance around a two dimensional shape, a measurement of the distance around something; the length of the boundary

Divisibility rules for numbers

The rules given below transform a given number into a generally smaller number, while preserving divisibility by the divisor of interest. Therefore, unless otherwise noted, the resulting number should be evaluated for divisibility by the same divisor. In some cases the process can be iterated until the divisibility is obvious; for others (such as examining the last  n  digits) the result must be examined by other means. For divisors with multiple rules, the rules are generally ordered first for those appropriate for numbers with many digits, then  Divisor Divisibility condition Examples 1 No special condition. Any integer is divisible by 1. 2 is divisible by 1. 2 The last digit is even (0, 2, 4, 6, or 8). 1294: 4 is even. 3 Sum the digits. The result must be divisible by 3. 405 → 4 + 0 + 5 = 9 and 636 → 6 + 3 + 6 = 15 which both are clearly divisible by 3. 16,499,205,854,376 → 1+6+4+9+9+2+0+5+8+5+4+3+7+6 sums to 69 → 6 + 9 = 15 → 1 + 5 = 6, which is clearly divisible by 3.

Scientific notation

To day iam going to teach the topic was scientific notation,Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10 - 9 . So, how does this work? We can think of 5.6 x 10 - 9  as the product of two numbers: 5.6 (the digit term) and 10 - 9  (the exponential term). Here are some examples of scientific notation. 10000 = 1 x 10 4 24327 = 2.4327 x 10 4 1000 = 1 x 10 3 7354 = 7.354 x 10 3 100 = 1 x 10 2 482 = 4.82 x 10 2 10 = 1 x 10 1 89 = 8.9 x 10 1  (not usually done) 1 = 10 0 1/10 = 0.1 = 1 x 10 - 1 0.32 = 3.2 x 10 - 1  (not usually done) 1/100 = 0.01 = 1 x 10 - 2 0.053 = 5.3 x 10 - 2 1/1000 = 0.001 = 1 x 10 - 3 0.0078 = 7.8 x 10 - 3 1/10000 = 0.0001 = 1 x 10 - 4 0.00044 = 4.4 x 10 - 4

Today

Today the first hour Iam going to the  class 7th std then I conduct the exam in the first chapter and then I am going to 10th std I write the sums in the blackboard after I teach that sums.And then I am going to 6th std I teach the exercise problem (exercise 1.1)and its objective type questions also I teach and then finally I give the home work.Then I am going to again the 7th std just discuss the second chapter introduction and then finally give the home work.

Today in my class

Today first hour Iam going to 7th class I teach the indirect variation that means two quantities are there one is decrease (increase)and another one quantity produce proportionate increase(decrease) is called inverse variation.And then explain the exercise problems.Then note correction.Iam going to next 10th std I write the sums solving the blackboard and teach.Then after iam going to 6th std i teach the exercise problem and solve with the help of blackboard.

Polynomials - Long Division

Image
A  polynomial  looks like this: example of a polynomial this one has 3 terms Dividing Polynomials can sometimes be divided using the simple methods shown on  Dividing Polynomials . But sometimes it is better to use "Long Division" (a method similar to  Long Division for Numbers ) Numerator and Denominator We can give each polynomial a name: the  top  polynomial is the  numerator the  bottom  polynomial is the  denominator
