Help please. There is theta and it's confusing.
(tan[theta])(1 + cot^2 theta)
cot[theta]
Also, I don't know how to put the symbols. So, if you can help with that I will be happy. =p
Edit:
I need help with this too.
(csc x)(sec x - cos x)
I got this so far..
(1/sin x)(1/cos x - cos x)
or is it wrong? Should I multiply the 2? Maybe put it in pythagorean identities? :/ I'll try these...but I need help so I can be sure.
