Degree of Polynomials

The highest value of the exponent in the expression is known as Degree of Polynomial. The degree of a polynomial is the largest exponent. It is also known as an order of the polynomial. While finding the degree of the polynomial, the polynomial powers of the variables should be either in ascending or descending order.
  1. Linear Polynomial: If the expression is of degree one then it is called a linear polynomial. For Example 5x+2,50z+3.
  2. Quadratic Polynomial: If the expression is of degree two then it is called a quadratic polynomial.For Example  2x^{2}+4x,3x^{2}+3x+3 .
  3. Cubic Polynomial: If the expression is of degree three then it is called a cubic polynomial.For Example  2x^{3}+5x,8y^{3}+6y+3 .
Example: Classify these polynomials by their degree:
  1. 7z^{3}+5z^{2}+1
  2. 5x-4
  3. 6x^{5}+8x^{3}-1
  4. 15y^{2}

Heron's Formula Hero of Alexandra  was a great mathematician who derived the formula for the calculation of the area of a  triangle  using the length of all three sides. This derived formula is called as  Heron’s formula . He also extended this idea to find the area of quadrilaterals and also higher order polygons. Derivation of Heron’s formula:

Today in my class I read some questions in the subject learning and teaching and then I read some questions in the subject contemporary India and education. Then I learnt how to make it the fixed table. Then I learnt about surya namaskar benefits and yoga. And then that benefits and steps follows in the figures.

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
