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

(1+tan^(2)A)/(1+cot^(2)A)= ..

(tan ^ (3) A) / (1 + tan ^ (2) A) + (cot ^ (3) A) / (1 + cot ^ (2) A) = sec A cos ecA-2sin A cos A

(1+ tan ^(2) A)/( 1 + cot^(2) A) equals

sin^(2)A*tan^(2)A+cos^(2)A*cot^(2) A= A) 1 + tan^(2)A + cot^(2) A B) tan^(2)A +cot^(2) A-1 C) 1 + sec^(2)A + tan^(2) A D) 1 + csc^(2)A + cot^(2) A

prove (1 + tan^2A) / (1 + cot^2A) = [(1 - tan A) / (1 - cotA)] ^2 = tan^2A

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

The value of cot^2 A-1/(sin^2 A) is equal to: cot^2 A-1/(sin^2 A) का मान किसके बराबर है?

( ( 1 + tan ^ 2 A )/( 1 + cot ^ 2 A )) = (( 1 - tan A)/ ( 1 - cot A )) ^ 2 = tan ^ 2 A
