Trapezoidal Approximation Problem x^2/2 Part 2 - Calculus
Free Calculus lecture presented by http://www.free-academy.com. This lecture explains how to estimate the area underneath the graph f(x)=x^2/2 between x=-2 and x=2. The technique used to do this is the trapezoidal approximation. Each base of the trapezoid is fixed to the actual graph and a straight line is drawn between them. The formula for the area can then be used to give a very accurate estimation of the area. Part 2 of 2.
