4. Press to display the result. 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. 4. Copy the result and evaluate. Thus, substituting X for S1, it can be seen that: ∫3x2 - 5dx= - 5x + ⎛ ⎜ 3⎜ ⎜ ⎝ ∂--∂--X--x---3-(--3--X Using mathematical functions 13-23
