Suppose we let
, so that
.
Also, recall the double angle identity for cosine:

So, we can rewrite and compute the integral using the substitution, as





Multiply 3 to the first bracket then multiply 2 to the second bracket. 3(a+2b) + 2(3a+b) = 3a+6b+6a+2b= 9a+8b
1 container = 55 balls
x 9 x 9
9 containers = ? balls
55 x 9 = 495
<u><em>The answer is 495 balls</em></u>
