A new way to find … in Problem 37: minimize

All points and vectors are in the $x y$ plane.

A new way to find $P$ in Problem 37: minimize $x^{2} + y^{2} = x^{2} + (\frac{10}{4} - \frac{3}{4} x)^{2}$ . By calculus find the best $x$ and $y$ .

This exercise builds on another exercise in its source book, which isn't shown here.
