I have the following problem... (Headbang)

First get the same denominator

Here its were I start to run into some confusion of distribution. I see the first fraction is correct but the second its not.. What am I doing wrong?

In the second fraction, the [1 + sin(x)] in the numerator and denominator needs to be in brackets, because you are multiplying the top and bottom by that entire expression.

I expect that they ARE equal, they just don't look it. There are many equivalent ways to write a trigonometric expression. What have you been told the "right" answer is?

Then you'll have to speak to your lecturer, as the answer is definitely correct.

It is well known my arithmetic is shocking, how could I think 9 + 9 = 10? Hahaha. Glad you finished it.
