I'm should be in college by now, but I didn't pass math and now I'm struggling with my last unit.
I know it seems to be quite simple, but I have no idea what the endgame is and can't get assistance with it as we're on our winter break.
I had the problem cscxsecx/csc^2 + sec^2 which I simplified to 1/sinxcosx
>cscxsecx/csc^2 +sec^2
>(1/sin)(1/cos) / (1/sin)^2 + (1/cos)^2
>sin^2 + cos^2 / sinxcosx
>1/sinxcosx
Is this correct?
Also, should 1-cos^2/sin simplify to sin?
>sin^2= 1-cos^2
>sin^2/sin= sin
I feel that it's wrong, but I'm not sure of what else to do with sin^2

Oi bro, I think the last part (1-cos^2/sin) might be correct, but the first I have no fucking clue.
May the calculator be with you!

No, it's not correct. You can check your answers on Wolfram Alpha (http://www.wolframalpha.com/input/?i=cscxsecx%2Fcsc%5E2+%2B+sec%5E2), by the way. I've attached my solution.

Thanks anon, I'll work on it a bit more later. I'm kind of a moron when it comes to math, but I'm sure it'll come around
>>
>>15800
Oh wait, not sure if it'd make a difference but it's set up kind of like this

Of course it makes a difference. 4/2 + 2 is not the same as 4/(2+2). Always include parentheses or write in proper notation when there's a risk of ambiguity.
Here is a correct simplification: http://mathb.in/49064

Obviously not OP, but kudos to all you mathy types.

No problem. Trigonometric simplifications are kind of bullshit, though.
