Question

If Sin2A = 2SinA.Then find A

Answer 1

Hey there!
Need a help!
Praneeth from Brainly.in here to help

Given

sin2A =2sinA

2sinAcosA=2sinA

cosA=1

A=cos^-1 (1)

A =0°

hope helped!!

Answer 2

Given,
sin2A = 2sinA
2sinAcosA = 2sinA
cancelling 2sinAon the both sides we get,
cosA = 1
cosA = cos0°
so, A = 0

hope it helps you!!
