Hi, I have problem that asks, "Prove that the equations are identities."
I tried for hours to solve it, but I'm lost... I would really appreciate it if someone could help me on this.
cot A + tan A + 1 = (cot A)/(1-tan A) + (tan A)/(1-cot A)
The stipulation is that I can only use the trigonometric identities that I've learned so far..
csc a = 1/sin a
sec a = 1/csc a
tan a = sin a/cos a
The pythgorean identities and Opposite angle formulas
So far I've tried switching it sines and cosines, tangent, and a few others but it never seems to come out right...
Thanks to anyone who can help.
