Tons of trig questions
I need to prove:
1. secx/(secx-tanx)=sec^2x+secxtanx
2. sin^3xcos^2x=sin^3x-sin^5x
3. sec^2x+csc^2x=sec^2xcsc^2x
4. (1-3cosx-4cos^2x)/sin^2x=(tanx-4)/(tanx+2)
5. csc^5x-cot^6x=1+3csc^2xcot^2x
6. (1+sinx+cosx)/(1+sinx-cosx)=(1+cosx)/sinx
I've always had A's in math but if i'm having this many problems should I get tutoring?
