What Are the Basic Rules for Evaluating Indefinite Integrals?

TL;DR

The basic rules for evaluating indefinite integrals include adding an 'x' term and a constant when integrating constants, and for variables raised to a power, increase the exponent by one and divide by the new exponent. Special techniques like u-substitution and integration by parts are used for more complex functions, while specific rules apply for trigonometric and exponential integrals.

in this video we're going to go over a few indefinite integral problems so what is the integral of 4 dx what is the answer for this problem the anti-derivative of a constant all you need to do is just add an x to it this is going to be 4x and you also need to add a a c value anytime you integrate a function there's always going to be a constant tha...
