To find the indefinite integral using formal variables

4.Press to display the result. Note: Use the arrow keys to view the entire function.

You could also just define

F1(x)= dx( sin(x2) + 2 cos(x)) .

For example, to find the indefinite integral of

3x2 – 5dx use:

(0, S1, 3 X 2 − 5, X )

1.Enter the function.

0

S1 3

X 5

X

2.Show the result format.

3.Press to close the show window.

4.Copy the result and evaluate.

Thus, substituting X for S1, it can be seen that:
