If 3sin alpha= 5sin beta then tan(alpha+beta/2) upon tan (alpha - beta/2) equals ? a. 1. b. 2. c. 3. d. 4 I want answer with full solution. Share with your friends Share 18 Ashwini Kumar answered this We have,3sinα=5sinβ⇒sinαsinβ=53⇒sinα+sinβsinα-sinβ=5+35-3 Using componendo and dividendo⇒2sinα+β2cosα-β22cosα+β2sinα-β2=82⇒tanα+β2tanα-β2=4Hence, d is correct option. 65 View Full Answer
