If `sin B=(sin(2A+B))/(5)` then `(tan(A+B))/(tan A)=?`

If sinB=1/5sin(2A+B), then (tan(A+B))/(tanA) is equal to

(sin2A + sin2B) / (sin2A-sin2B) = (tan (A + B)) / (tan (AB))

Given sin B=(1)/(5)*sin(2A+B) then tan(A+B)=k tan A, where k has the value equal to

If tan A=(1-cos B)/(sin B), then tan2A=tan B

In a Delta ABC if tan B=(2sin A sin C)/(sin(A+C)) then tan A,tan B,tan C are in

sin B=3sin(2A+B), prove that2tan A+tan(A+B)=0

If A=B=60o, verify that cos(A-B)=cos A cos B+sin A sin B(iii)sin(A-B)=sin A cos B-cos A sin B(iii)tan(A-B)=(tan A-tan B)/(1+tan A tan B)

If A and B are acute angles and (sin A)/(sin B)=sqrt(2) and (tan A)/(tan B)=sqrt(3), find A and B

If sin2A=lambda sin2B prove that ((tan(A+B))/(tan(A-B)))=(lambda+1)/(lambda-1)

If A+B+C=pi and sin(A+(C)/(2))=k sin((C)/(2)) then (tan A)/(2)(tan B)/(2) is
