Is

sin(6x)/sin(2x) = sin(3x)

?

If not, then what would be the correct way of expressing this?

Any input would be greatly appreciated!

Thanks in advance!

sin(6x)/sin(2x) = sin(3x)

(2sin 3x cos 3x)/sin 2x = sin 3x,

that red thing (sin 2x) SHOULD be cos 3x, and 2 should be introduced to the RHS, to generate an identity. . . . see below

(2sin 3x cos 3x)/cos 3x = 2 sin 3x
