Question

Prove that (cosec teta-coto teta) ^2 =1- cos teta/1+cos teta​

Answer 1

Answer:

(cosec x-cot x)^2 = ((1-cos x)/(1+cos x))

[(1/sin x) - (cos x/sin x)]^2 = [2.(sin (x/2))^2]/[2.(cos (x/2))^2]

((1-cos x)/sin x)^2 = [tan(x/2)]^2

{[2.(sin (x/2))^2]/[2.sin(x/2).cos (x/2)]}^2 = [tan(x/2)]^2

[sin(x/2) / cos(x/2) ]^2 = [tan(x/2)]^2

[tan(x/2)]^2 = [tan(x/2)]^2
