Quote of the Day: "On the other hand, it is impossible for a cube to be written as a sum of two cubes or a fourth power to be written as a sum of two fourth powers or, in general for any number which is a power greater than the second to be written as a sum of two like powers. For this I have discovered a truly wonderful proof, but the margin is too small to contain it." -- P. Fermat Objectives: The student will use the trapezoidal rule to approximate a definite integral. The student will use Simpson's rule to approximate a definite integral 1. Collect homework. 2. Recall that when we first began the study of integrals, we used Riemann sums with rectangles to approximate the area under a curve. Now we will look at two other methods of approximating the area under the curve. (a) Trapezoidal Rule Approximate the area using trapezoids:
(b) Simpson's Rule Based on a formula to find area under parabolic arc:
