Question

if sin ( alpha+bita)/sin(alpha-bita)=a+b/a-b then prove that a tan bita=b tan alpha​

Answer 1

Step-by-step explanation:

sin(alpha+beta),sin(alpha-beta)=(a +b),(a-b) =>(tanalpha),(tanbeta)= ... sin(α+β)sin (α-β)=a+ba-b⇒tanαtanβ= Related ... If ` sinalpha+sin beta=a and cos alpha+cos beta= b. play.
