Simplify `(1+tan^2theta)+(1+tan^2theta)`

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

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

Simplify: (1+tan^(2)theta)(1-sintheta)(1+sintheta)

tan2 theta xx tan theta=1

Simplify (1 + tan ^(2) theta ) ( 1 + sin theta ) ( 1 - sin theta )

Prove that (1+ tan^4 theta)/(1+ tan^2 theta) = sec ^2 theta-2 sin^2theta

Prove that : (1 - tan^(2) theta)/(1 + tan^(2) theta) = cos^(2) theta - sin^(2) theta

If (1+tan^2 theta)+(1+ (tan^2 theta)^-1)=k , then sqrtk =? यदि (1+tan^2 theta)+(1+ (tan^2 theta)^-1)=k ,है, तो sqrtk =?

tan2 theta tan theta=1
