Question

olve : sin 2x – sin 4x + sin 6x = 0​

Answer 1

Answer:

HELLO...

Step-by-step explanation:

sin 2x – sin 4x + sin 6x = 0

sin8x=0

hence,

sin8x.

hope it's helps you.....

Answer 2

Answer:

2sin(4x)cos(2x)=sin(4x)

sin(4x)(2cos(2x)-1)=0

Hence either sin(4x)=0 or cos(2x)=1÷2

in case 1

x=0,π/2,2π....are solutions

in case 2

x=π/6 is a solution.
