Homework Statement
Derivative of Sin22x
Homework Equations
dy/dx = dy/du * du/dx
y=U2
The Attempt at a Solution
Just want to make sure I am doing this right*.
Do I let U = Sin2x or U = 2x?
Let's say U = Sin2x
y=U2
then y` = 2Sin2x * cos2x?
Or if U = 2x.
y = SinU2
y` = 2cos2x * 2
y` = 4cos2x
am i on the right track with either of these? any help is appreciated! thanks!
