Numerical integration direct from the keyboard?

[Joe Horn]

Sounds like you're in Home view. In CAS view, all three examples in the built-in Help screen for int() work. I personally use the integrate template (the key between the toolbox key and the x-t-theta-n key) in Textbook entry mode so that I don't have to remember the syntax of int().

N.B. Before doing any symbolic work on x, be sure that it contains no value. You might have to del(x).
