Prove that:- cosec2x + cot2x = cotx
Solve trig equation cot(2x)=-1
Verify Trig Identity cot(2x) = (cot^2 -1)/(2 cot x). Double Half Angle Formula
cos(2x) = (cot^2x - 1) / 2cotx
prove (1 + cot^2(x) = csc^2(x)
Prove the trig identity: 1+cot^2 = csc^2
cot(2x) = 1/2(cotx - tanx)
Get cosec^2x -cot^2x =1 from sin^2x+cos^2x=1
