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

(tan A + tan B)/( cot A + cot B)+(1- tan A tan B)/( 1- cot A cot B)=

Prove that (tan alpha+tan beta)/(cot alpha+cot beta)=tan alpha tan beta

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

(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

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

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