Integrating Equations 8-5
Enter the expression that defines the integrand's function:
If the calculator attempted to evaluate this function at x = 0, the lower limit of
integration, an error ( ) 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.
Now integrate this function with respect to x (that is, X) from zero to 2 (t = 2).
