In this video, I calculate an integral by converting it into a double integral and using Fubini’s theorem. Behold the power of multivariable calculus. Enjoy!

A cable of 80 meters (m) is hanging from the top of two poles that are both 50 m from the ground. What is the distance between the two poles, to one decimal place, if the center of the cable is (a) 20 m above ground? (b) 10 m above ground?
