Find the circumference of an ellipse, rely on numerical methods to evaluate it

x = 4cost An ellipse is defined by the parametric equation (Parametric equation will be a topic that we will y = 5sint discuss shortly but you do not really need to know it to do this problem) dx The circumference is defined as: C = dt 1. Use Desmos parametric graphing feature to draw this ellipse 2. Clearly construct the circumference integral. You can use 7 = 3.1416 3. Use trapezoidal rule with n = 50 to approximate the circumference of this ellipse
