I can’t do it.

A particle is moving along the parabola y=x^2 (y equals x squared) in the first quadrant in such a way that its x-coordinate is (measured in meters) increasing at a steady 10 meters/sec. How fast is the angle of inclination theta of the line joining the particle to the origin changing when x=3 meters?

Oh my god. I know enough to understand what it wants, but in no way do I understand how to do it.

Calculus is hard.
