tomorrow i have a math exam that i need to pass, i am completely disorganized meaning i can't find my notes. i don't understand factoring such as what would be needed to solve(prove) something like this:

csc(x)-sin(x)csc(x)=csc(x)cos(^2)(x)

I have this on Thursday

I'll help a fellow Nova Scotian out as much as I can.

This Chart is pretty helpful.

These are proofs and you're trying to make your left side = to your right.
I dunno a very in-depth explanation but when all else fails, write all your things in terms of sin and cos.

I don't feel like doing the problem for you, but there's a great tutorial I found to help on these instances of layered trigonometry an such. http://www.youtube.com/watch?v=3GqJgiZtdEU

Your own fault.

I think you have to convert some of the identities until one side equals the otherside... but I'm not really sure what your question is. I'll be taking a test on that stuff soon as well. Good luck.

not paying attention, not taking notes and not doing my homework all seemed like a good idea at the the time but now i'm ****ed

wouldn't you put the variable in for x and solve? it seems like common sense to me..

Are you retarded?

And on another note, the OP is a bit lax in the head as well. The problem you posted involves you taking the left side and converting it to the right side via trig identities. (i.e.- csc(x) = 1/sin(x)). Have fun with that test bud.

If you need to factor something, buy a TI-89 Titanium.

Factors, expands, solves for x, etc.

If you have a formula sheet. You know the different formulas for the trignometric ratios you could technically figure out the answers, but in the given time without any practise that's going to be pretty darn hard.

I suggest practising questions you atleast know the answers to. That may help...
