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?
First of all, you MUST use brackets where they are needed. Please review what you have written. However, I can see your thought process and what you have ended up with is a correct answer. Why do you think it's incorrect?

Did I overuse them, or did I just not place them in the right position?
Maybe I'm not trying hard enough, I'll give it a couple more tries.
Re: Perform Addition and simplify trigonometric expression
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.

Correct up to here. But you can not cancel off any sin(x) values because your factor on the bottom is not sin(x), it's [ 1 + sin(x) ]. This is the furthest you can go.

Actually when I use the calculator this equation is not equal. I don't mean to nag you about this, but I'm really trying different options and none of my answers work.
Re: Perform Addition and simplify trigonometric 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?

It's an online course I'm redoing a homework I din't get 100% on and It's telling me, its not the right answer.
