What is the integration of X²?
Integration Rules
| Common Functions | Function | Integral |
|---|---|---|
| Square | ∫x2 dx | x3/3 + C |
| Reciprocal | ∫(1/x) dx | ln|x| + C |
| Exponential | ∫ex dx | ex + C |
| ∫ax dx | ax/ln(a) + C |

- =e2x+C.
How do you find the definite integral from 1 to 2?
We find the Definite Integral by calculating the Indefinite Integral at a, and at b, then subtracting: We are being asked for the Definite Integral, from 1 to 2, of 2x dx. First we need to find the Indefinite Integral. Using the Rules of Integration we find that ∫2x dx = x 2 + C. Now calculate that at 1, and 2:
What integrals does the integral calculator support?
The Integral Calculator supports definite and indefinite integrals (antiderivatives) as well as integrating functions with many variables. You can also check your answers! Interactive graphs/plots help visualize and better understand the functions. For more about how to use the Integral Calculator, go to ” Help ” or take a look at the examples.
Why can’t we integrate products as a product of integrals?
Recall that we can’t integrate products as a product of integrals and so we first need to multiply the integrand out before integrating, just as we did in the indefinite integral case. Also, don’t get excited about the fact that the lower limit of integration is larger than the upper limit of integration.
What happens if the point of discontinuity occurs outside of integration?
If the point of discontinuity occurs outside of the limits of integration the integral can still be evaluated. In the following sets of examples we won’t make too much of an issue with continuity problems, or lack of continuity problems, unless it affects the evaluation of the integral.
