Prove the following: `(1 - cos2theta)/(1 + cos2theta)` = tan2θ

English

Prove the following: 1-cos2θ1+cos2θ = tan2θ - Mathematics and Statistics

Prove the following:

`(1 - cos2theta)/(1 + cos2theta)` = tan²θ

Sum

L.H.S. = `(1 - cos2theta)/(1 + cos2theta)`

= `(2sin^2theta)/(2cos^2theta)`

= tan²θ

= R.H.S.
