603-4 Integration Calculations [OPTN]-[CALC]-[∫dx]To perform integration calculations, first display the function analysis menu andthen input the values in one of the formulas shown below.Gauss-Kronrod Rule4(∫dx) f(x) , a , b , tol )∫ ( f(x), a, b , tol) ⇒ ∫ab f(x)dxSimpson’s Rule4(∫dx) f(x) , a , b , n )∫ ( f(x), a, b, n) ⇒ ∫ ab f(x)dx, N = 2nAs shown in the illustration above, integration calculations are performed bycalculating integral values from a to b for the function y = f (x) where a < x < b, andf (x) > 0 *. This in effect calculates the surface area of the shaded area in theillustration.* When f (x) < 0 on a < x < b, the surface area calculation produces negativevalues (surface area below the x-axis).k Changing Integration Calculation MethodsThis calculator can use either Gauss-Kronrod Rule or Simpson’s Rule to performintegration calculations. To select a method, display the set up screen and selecteither “Gaus” (for Gauss-Kronrod Rule) or “Simp” (for Simpson’s Rule) for theIntegration item.All of the explanations in this manual use Gauss-Kronrod Rule.Area of ∫ab f(x)dx is calculatedToleranceEnd pointStart pointNumber of divisions (value for nin N = 2 n,nis an integer from 1 through 9)End pointStart pointP.6
