Note: Use the arrow keys to view the entire function. | To find the indefinite integral using formal variables 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.
