What is polythene? What are examples of sports materials made from polythene?

Polythene or Polyethylene or polyethene is a polymer made
of units of ethene or ethylene. Ethene has the molecular formula C2H4 with the two
carbon atoms linked together by a double bond as H2C=CH2. When ethene is made into a
polymer there are carbon atoms linked to each other with a single bond in long chains;
each carbon atom has two hydrogen atoms attached to
it.


Polyethene is the most widely used plastic in the
World. It has a very long life as the bio-degradation of polyethene takes 250- 300
years.


In the field of sports, polyethene has several uses.
Nets used in soccer, basketball, badminton etc. are made of polyethene. The plastic
finds extensive use in making protective gear for all sports. Polyethene is also used in
making sports clothing, shoes, etc. along with other fabrics.

Calculate tan(x-y), if sin x=1/2 and sin y=1/3. 0

We'll write the formula of the tangent of difference of 2 angles. tan (x-y) = (tan x - tan y)/(1 + tan x*tan y) ...
