this is for proving identies and its fustrating i can't solve this one question! lol x=feta (btw the first part is supposed to be divided by the bottom) 1 + 2sinxcosx + sinxcosx sinx + cosx (1 + 2sinxcosx / sinx + cosx) + sinxcosx

Prove the identity: 1cos2x/sin2x = 1+tanx/1+cotx I simplified the RS to tanx. LS:(12cos²x+1)/2sinxcosx (2+2cos²x)/2sinxcosx How do I simplify the rest?

Solve: cos(2x180)  sin(x90)=0 my work: cos2xcos180 + sin2xsin180= sinxcos90  sin90cosx cos2x  sin2x= cosx cos^2x + sin^2x 2sinxcosx=cosx I'm stuck here. I tried subtracting cosx from both sides and making sin^2x into 1

Solve identity, (1sin2x)/cos2x = cos2x/(1+sin2x) I tried starting from the right side, RS: =(cos²xsin²x)/(1+2sinxcosx) =(cos²x(1cos²x))/(1+2sinxcosx) and the right side just goes in circle. May I get a hint to start off?
