Homework Help: Calculus

Posted by Jim on Tuesday, November 15, 2011 at 5:06pm.

With y=f(x) (2x-10)^1/2
having a virtual line joined at point Q from the origin (0,0), determine the coordinates of point Q that maximises the angle of vision of an observer, situated at the origin, following the movement of point Q along the curve.

Note that tan (theta symbol) = y/x


Will I just have to find both derivatives and from there find the zero for the maximum?
