Prove: (cot A+tan B)/(cot B+tan A)=cot A tan B

Show that (cot A + tan B) / (cot B + tan A) = cot A. tan B.

Prove that : (cot A + tan B)/ (cot B + tan A) = cot A tan B

If,A,B,C are angles of a triangle and if none of them is equal to (pi)/(2) ,then tan A+tan B+tan C is cot A cotB cot C tan A tan B tan C sin A sin B sin C cos A cos B cos C

Show that in a Delta ABC (cot B+cot C)/(tan B+tan C)+(cot C+cot A)/(tan C+tan A)+(cot A+cot B)/(tan A+tan B)=1

If A+B+C=pi, prove that (tan A)/(tan B tan C)+(tan B)/(tan Atan C)+(tan C)/(tan A tan B)=tan A+tan B+tan C-2cot A-2cot B-2cot C
