" 42."(cos A)/(1-tan A)+(sin A)/(1-cot A)=sin A+cos A

Show that (cos A)/(1-tan A)+(sin A)/(1-cot A)=sin A +cos A

Prove the following identities: (cos A)/(1-sin A)+(sin A)/(1-cos A)+1=(sin A cos A)/((1-sin A)(1-cos A))((1+cot A+tan A)(sin A-cos A)/(sec^(3)A-cos ec^(3)A)=sin^(2)A cos^(2)A

Prove that : (cos A)/ (1 - tan A) + (sin A)/ (1- cot A) = sin A + cos A

Prove that (cos A)/(1-tan A) + (sin A)/(1-cot A) = cos + sin A .

Prove that : (cos A)/ (1 - tan A) + (sin A)/ (1 - cot A) = cos A + sin A

Prove that cos A/(1 - tan A) + sin A /(1 - cot A) = sin A + cos A

Prove the following identities: (cos A)/(1-tan A)+(sin A)/(1-cot A)=cos A+sin A

sin A(1+tan A)+cos A(1+cot A)=sec A+cos ecA

(1 + cot A + tan A) (sin A-cos A) = sin A tan A-cot A cos A

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