" 55.(i) "(cot A+tan B)/(cot B+tan A)=cot A tan Bquad " (ii) "(tan A+tan B)/(cot A+cot B)=

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

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

frac(tan A + tan B)(cot A + cot B) is equal to

If A+B+C= (pi)/(2) prove that:m (i) "tan"A tan B +"tan"B tan C +"tan" C tan A =1 (ii) cot A +cot B+ cot C= cot A cot B cot C.

If 2 tan A + cot A = tan B , then cot A +2 tan (A-B)=

If tan A=cot B, then A+B is equal to
