Problem B. 4738. (October 2015)
B. 4738. \(\displaystyle C\) is an arbitrary point of a circle \(\displaystyle k\) of diameter \(\displaystyle AB\), different from \(\displaystyle A\) and \(\displaystyle B\). Drop a perpendicular from \(\displaystyle C\) onto diameter \(\displaystyle AB\). The foot of the perpendicular on line segment \(\displaystyle AB\) is \(\displaystyle D\), and the other intersection with the circle \(\displaystyle k\) is \(\displaystyle E\). The circle of radius \(\displaystyle CD\) centred at \(\displaystyle C\) intersects circle \(\displaystyle k\) at points \(\displaystyle P\) and \(\displaystyle Q\). Let \(\displaystyle M\) denote the intersection of line segments \(\displaystyle CE\) and \(\displaystyle PQ\). Dertermine the value of \(\displaystyle \frac{PM}{PE} + \frac{QM}{QE}\).
