I agree with HallsofIvy. You need to review the unit circle. Sin(2(22.5 degrees))= (2^.5)/2

It should read 2x^2 - 4x. My mistake. And I forgot all about solving for the constant first...whoops! I figured it out, though. Thanks! ^.^

Does that mean that U(x) would have to be an absolute value function?

Sine equals √2/2 when θ= 45°, 135°, etc. That should help

Homework Statement The figure below shows the force exerted on a particle that moves along the x-axis. Draw a graph of the particle's potential energy as a function of position from x=0 to x=1.1 . Let U be zero at x=0.Homework Equations F=-dU/dxThe Attempt at a Solution I decided to divide the...
