How to plot an integral on Prime?

[Han]

Try this alternate method:

In the CAS, create a function like so:

f(x):=int(tan(t^2),t,0,x);

Then in the [Symb] view, use f(X) as your formula. (Note upper vs lower case) I generally prefer this method since it means I can use the function f for other calculations as well as graphing.
