2.7.58 Programming Tutorial Exercise 1

Just enter the formula ‘ninteg(sin(t)/t, t, 0, x)’, type Z F, and answer the questions. Since this formula contains two variables, the default argument list will be ‘(t x)’. We want to change this to ‘(x)’ since ‘t’ is really a dummy variable to be used within ninteg.

The exact keystrokes are Z F s Si RET RET C-b C-b DEL DEL RET y. (The C-b C-b DEL DEL are what fix the argument list.)
