find the length of the ladder if the distance from the bottom of the ladder to the building is 9 feet.
I answered a nice question on WyzAnt about approximating roots to a quadratic equation that had real but irrational roots. Calculus enables us to find rational approximations to these irrational roots. I will re-present the solution to the problem, and continue to find a general expression to do this for an arbitrary polynomial. "Problem: approximate... read more
