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:
