Maximum Radius of Circle
Optimization Problem with Solution
Use the derivative to find the size of an angle of a right triangle so that the radius of the circle inscribed is maximum; for a constant hypotenuse.
Problem: ABC is a right triangle and r is the radius of the inscribed circle. a) Express r in terms of angle x and the length of the hypotenuse h. b) Assume that h is constant and x varies; find x for which r is maximum.
