Question

If cos A = 1/2 and sin B = 1/root 2, find the value of: tan A _tan B / 1+tan A tan B

Answer 1

see here...
I hope u understand it...
please mark it as a brainieist answer......

Answer 2

heya,..
cosA=1/2..

cosA=cos60°

A=60°

and again.SinB=1/√2

sinB=sin45°

B=45°

,now ,tanA-tanB/1+tanA*tanB=Tan(A-B)

tan(60°-45°)

tan15°=√3-1/√3+1 Ans

hope it help you.
