1. Sketch the area. 2. Determine the boundaries c and d, 3. Set up the definite integral, 4. Integrate. Ex. 3. Find the first quadrant area bounded by the following curves: y x2 2, y 4 and x 0. (There are two ways to solve this problem: we can calculate the area between two functions
Use your expression in a and integration to find an estimate for the area of R. Use the trapezium rule with 6 equally-spaced ordinates to find another estimate for the area of R. 8= x2 + 16xR4 xThe diagram shows the curve. = x2 + 16 for x > 0.Show that the stationary point on the curve.
