RE: (35S) Quick integration
It appears that the command on line 2 got lost in translation:
STO B Also RCL +A should rather be: RCL *A (11-14-2022 05:05 AM)Roberto Volpi Wrote: ∫(sinX/X) dx in interval [0,2] that may not be evaluated by the native HP35S integrator From the HP 35s scientific calculator user's guide (p. 8-5): Quote:If the calculator attempted to evaluate this function at x = 0, the lower limit of integration, an error (DIVIDE BY 0) would result. However, the integration algorithm normally does not evaluate functions at either limit of integration, unless the endpoints of the interval of integration are extremely close together or the number of sample points is extremely large. The given result is: 1.6054 (11-12-2022 05:13 PM)Albert Chan Wrote: Your example, ∫(√(1+x^2), x = 0..1) ≈ 1.47894285754 That should be: ∫(√(1+4x^2), x = 0..1) ≈ 1.47894285754 |
