cos 2 theta is not equal to ................... A) 2 cos ^(2) theta -1 B) 1- 2 sin ^(2) theta C) (1+ tan ^(2) theta)/( 1- tan ^(2) theta) D) (1- tan ^(2) theta)/(1+ tan ^(2) theta)

theta = tan^(-1) (2 tan^(2) theta) - tan^(-1) ((1)/(3) tan theta) " then " tan theta=

Find, theta =tan^(-1) (2 tan^(2) theta) - tan^(-1) ((1)/(3) tan theta) " then " tan theta=

theta = tan^(-1) (2 tan^(2) theta) - tan^(-1) ((1)/(3) tan theta) " then " tan theta=

theta = tan^(-1) (2 tan^(2) theta) - tan^(-1) ((1)/(3) tan theta) " then " tan theta=

simplify (1+tan^(2)theta)+(1+(1)/(tan^(2)theta))

(1 + tan^(2) theta)/(1 - tan^(2) theta)=
