Integration By Substitution - Introduction In differential calculus, we have learned about the derivative of a function, which is essentially the slope of the tangent of the function at any given point. Click here to start. Since the derivative of a constant is 0, indefinite integrals are defined only up to an arbitrary constant.

First of all I would like to start off by asking why do they have different change of variable formulas for definite integrals than indefinite...why cant we just integrate using U substitution as we normally do in indefinite integral and then sub the original U value back and use that integrand for definite integral?. If you don’t change the limits of integration, then you’ll need to back-substitute for the original variable at the end. I am currently planning my future quarters at university and I have run into a bit of an issue: A full quarter at my school is 15 credits per quarter and each of the higher-end math and physics classes is only 3 credits, meaning I would need to take 5 classes per quarter. u = 4 – x. du = (-1)dx. U-substitution in definite integrals is just like substitution in indefinite integrals except that, since the variable is changed, the limits of integration must be changed as well.
