Question

Solve sin 4x = sin 2x​

Answer 1

Answer

npi +/- pi/6 and n(pi)÷2

Step-by-step explanation:

sin4x=sin2x

2sin2xcos2x=sin2x

sin2x=0 or cos2x=1/2

2x=n(pi) or 2x =2n(pi) +/- (pi)/3

x=n(pi)/2 or x=npi +/- pi/6

Answer 2

Answer:

chineej equal to 4 into x is equals to rs. in 2x

2 into 2 into 2 into equal to sin 2x

sin 2x 2x equals to 1 by 2

200 and 500 to x is equals to 2 by minus

H2 npi by 2 or equal to n p i p s
