I am having a terrific time with verifying my trig identities. I have done ALL odd probs in my text, and am repeating them. The problem that I am having is that I do not see a clear path from one side of the expression to the other side.

My methods are crude, and I always start by writing everything in terms of sin and cos. Then I like to eliminate fractions, but those 2 methods are not proving to be much help.

With the simple 2 or 3 step proofs, I can do well, but when I have to do more than that, I'm like a 3 year old with a TI-84. I might be able to do some stuff with it, but it gets me nowhere, and I don't understand what Its doing.

So here is one problem that I am working on. I have the solution manual for my text, so I use that for moving along, but I would appreciate ANY input that you might think is helpful for me.

cosxcotx

-------- - 1 = cscx

1-sinx

I know some of you might just peek at it, and know how to do it, but I have wasted almost 2 pages of paper writing and re-writing this problem! help me please

cosx cosx

----

sinx

----------- - 1

1-sinx

-1 being changed to 1-sin^2x, and reduced to:

cosx cotx - (1-sinx)

-------------------

1-sinx

this is where I get lost. I can look at the solution manual and get their resolution, but I still don't look at it and see anything.

Thanks for having such a helpful forum, Jenny
