find derivative of inverse sin(sqrt(2t)) PLLLLLZ HEEELLP!

the problem says to find the derivative of inverse sin(sqrt(2t)).
I know the general equation for inverse sin(u)= (1/sqrt(1-u^2))(du/dx).
im having a hard time first finding the derivative of sqrt(2t). i know the chain rule and power rule is used but i dont know how.

Hi diamondeyes;

You have

Say:

Now you have

By the chain rule:

So all you need now is:

and

and then you just plug those two derivatives into the chain rule. Can you take it from here? If not, take a peek.
