Prove the following identities,where the angles involved are acute angles for which the expressions are defined. ((1+tan^(2)A)/(1+cot^(2)A))=((1-tanA)/(1-cot A))^(2)=tan^(2)A

Prove the following identities, 0^(@) le theta le 90^(@) . (x) (1+tan^(2)A)/(1+cot^(2)A) = ((1- tanA)/(1- cot A))^(2) = tan^(2)A

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

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

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

Prove the following identities, where the angles involves are acute angles for which the expressions are defined:(x) ((1+tan^2A)/(1+Cot^2A))^2=((1-tan^2A)/(1-Cot^2A))^2=tan^4A

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

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

Prove: (1+tan^(2)theta)/(1+cot^(2)theta)=((1-tan theta)/(1-cot theta))^(2)=tan^(2)theta

What is (1+ tan^(2) theta)/(1+cot^(2) theta) -((1-tan theta)/(1-cot theta ))^(2) equal to ?
