This calculus video tutorial explains how to calculate the arc length of a curve using a definite integral formula. This video contains plenty of examples and practice including integration techniques such as u-substitution, factoring the gcf, factoring perfect square trinomials and simplify radicals. This video shows you how to find the arc length in terms of x and in terms of y values. Here are the steps. First, find the first derivative of the function using the power rule or chain rule. Next, plug everything into the definite integral formula and integrate it using the limits of integration that are provided.
