Express the given function as a composition of 2 simple functions (x^3-x^2+2)^7.

In odrer to express the function into two dsimple
fuctions, you need to to:


1. Assume that (x^3 - x^2 + 2)=
f(x)


Now, assume g(x) = x^7


by
replacing x with f(x) you will get g(f(x)) =
[f(x)]^7


  but,  (x^3-x^2+2)^7 = [f(x)]^7 )= g(f(x)so we
can compose the function as follow:


g(f(x)) =
(x^3-x^2+2)^7, while f(x)= 9x^3-x^2+2)^7

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) ...
