Question

does sinx+sin2x = sin3x
is it additive

Answer 1

What do you think?

Answer 2

no its not

Answer 3

that is what I thought kky10997 thank you.

Answer 4

so just you need prove it that

sinx +sin(x+x) = sin(2x+x)
use formula sin(a+b) = ...

hope you learned it sure

Answer 5

im trying to simplify\[2\sin2x-2sinx+2*\sqrt{3} cosx-\sqrt{3}=0\]
can someone give me a hint as to where to start?
