Example: Follow the steps to calculate the area between f(x) Bx and the x-axis, on the interval 12, 18 using Riemann sums la) Sketch the area that we want to find many rectangles do we need, to make sure we get the true área Inot an approximation)? lot ä¿ te) Divide the interval [2, 18] into N equal subdihisions of length Ax. (d) if we useå²to denote the nght-hand endpoint of the kih rectangle, what is xÇ in terms of k and N? lel Simplify Given: Atl [f) Areas Note: for this particular shape, we would work out the true area by finding the area of the big triangle, and subtracting the area of the smaller triangle. We get the same answer
