Question

if sinx=nsin(x+2A), show that:-tan(x+A)=(1+n/1-n) tanA

Answer 1

Hey mate,

⚡here is your answer

⭐sin(x+2a) / sin(x) = 1/n

[sin(x+2a) + sin(x)] / [sin(x+2a) – sin(x)] = (1+n) / (1-n)

(:.Using componendo and dividendo)

2.sin(x+a).cos(a) / 2.sin(a).cos(x+a) = (1+n) / (1-n)
tan(x+a) / tan(a)

= (1+n) / (1-n)tan(x+a)

I hope it helps.
⭐mark it as brainliest.

= (1+n) × tan(a)/ (1-n)
