Hey, I am just starting my trig identities unit and I have a question I'm stuck on.. it's probably very easy, so bear with me and don't make fun of me ^^
(sec˛x + csc ˛x) - (tan˛x - cot˛x)
So I have ( 1/cos˛x+ 1/sin˛x) - (sin˛x/cos˛x+ cos˛x/sin˛x)...
i suppose you want to simplify here? that's good. now just combined the fractions in each set of brackets. then combine the two resulting fractionsQuote:

can I change the cos˛x and sin˛x to 1 and have it as 1+1= 2?
Hello, Slipery!
Your work is correct, but are you aware of these identities?

Simplify: . - (\tan^2\!x + \cot^2\!x))
We have: .
Ahhh, that is very helpful. thank you both soroban and jhevon.
I honestly think my brain has issues with this type of work, it just wont' draw the connections.
