Prove the identity:
(cosθ - sinθ) / (cosθ + sinθ) = sec2(θ) - tan2(θ)
thanks so much! show work please.
3 AnswersMathematics12 months agoMath Identities qsts, will award best answer, pls help?
prove the following:
1. (cosθ/ secθ -1) + (cosθ/ secθ +1) = 2cot^2*θ
2. (sinθ + tanθ) / (cosθ +1) = tanθ
3. (1-cos 2θ) / (sin 2θ) = tanθ
Answering even one question would be helpful, thanks so much!
