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 10424327 = 2.4327 x 104
1000 = 1 x 1037354 = 7.354 x 103
100 = 1 x 102482 = 4.82 x 102
10 = 1 x 10189 = 8.9 x 101 (not usually done)
1 = 100
1/10 = 0.1 = 1 x 10-10.32 = 3.2 x 10-1 (not usually done)
1/100 = 0.01 = 1 x 10-20.053 = 5.3 x 10-2
1/1000 = 0.001 = 1 x 10-30.0078 = 7.8 x 10-3
1/10000 = 0.0001 = 1 x 10-40.00044 = 4.4 x 10-4

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:

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
