(1+(1)/(tan^(2)theta))(1+(1)/(cot^(2)theta))=(1)/(sin^(2)theta-sin^(4)theta)

Prove that : (1 + tan^(2) A) + (1 + (1)/ (tan^(2) A)) = (1)/ (sin^(2) A - sin^(4) A)

Prove: (1+tan^2A)+(1+1/(tan^2A))=1/(sin^2A-sin^4A)

Prove each of the following identities : (1+ tan^(2) theta)(1+ cot^(2) theta)=(1)/((sin^(2) theta- sin^(4) theta))

(tan A)/((1+tan^(2)A)^(2))+(cot A)/((1+cot^(2)A)^(2))=sin A cos A

If 3 cot A = 4 , check whether (1-tan^(2)A)/(1+tan^(2)A)=cos^(2)A-sin^(2)A is true or not.
