[SOLVED] Optimization problem
A Norman window has the shape of a semicircle atop a rectangle so that the diameter of the smicircle is equal to the width of the rectangle. What is the area of the largest possible Norman window with a perimeter of 28 feet?
After solving for b and plugging b into the Area formula I cannot determine the local max. Is the algebra or derivative wrong?
