Here's the general idea: Use the differentiate function
(i.e., 'd(' function). You will differentiate with respect to x but the function
will be a definite integral (i.e., the integrate function). The
integrate function will have the following arguments: the integrand function in terms of ,
the independent variable tt, the lower limit, then the upper limit. |
