Is the answer 36?
-
Well the lack of parentheses makes it hard to know what the question really is, but I think that you mean
(36 * sin^2(t)) + (36 * cos^2(t)) in which cased, yes the answer is 36.
The solution should go something like this. Factor out the 36.
Now you have 36 * (sin^2(t) + cos^2(t))
Since (sin^2(t) + cos^2(t)) = 1 we get
36 * 1 = 36
So your answer is correct.
