I've been working on these for a few hours now and can't make any progress. I need to simplify one side using trig identities to get it to equal the other side.
2 - sec(x)^2 = 1 - tan(x)^2
So far I have:
2 - (1 + tan(x)^2) = 1 - tan(x)^2
The second one is:
sin(x) + cos(x)cot(x) = csc(x)
I tried starting this one in 2 ways, but don't seem to be making any progress with either.
Attempt 1:
sin(x) + (1/sec(x)) * (1/tan(x)) = csc(x)
Attempt 2:
sin(x) + (sin(x)/(tan(x)) * (1/tan(x)) = csc(x)
Thanks a lot for any help.
