# Math Help - The value of Sinx

1. ## The value of Sinx

Hi,

If g(x) = sin2x,

what is g o g? I know that the composite equation results in sin2(sin2x), but have a limited grasp on the laws of the sine function- how would you go about expressing it further?

thank you.

Do you mean:

$g(x)=\sin^2(x)$

or

$g(x)=\sin(2x)$

??

3. I mean g(x) = sin (2x)
