Question

cos^2 theta / cot^2 theta - cos^2 theta=3

Answer 1

Cos^2theta/cot^2theta-cos^2theta=3 or, sin^2theta-cos^2theta=3....(1) (because cos^2theta/cot^2theta =sin^2 theta). In the rule of trigonometry sin^2theta+cos^2theta=1 ...(2) we get 1 and 2 .sin^2theta-cos^2theta+sin^2theta+cos^2theta=3+1 or, 2sin^2theta =4 so sin^2theta=2 and cos^2theta=1 ( 1-2) and cot^2 theta= cos^2theta/sin^2theta=1/2 . If you do not under stand any thing please comment
