Z cos 2x 1 dx a let u 2x 1.
U substitution problems math. In essence the method of u substitution is a way to recognize the antiderivative of a chain rule derivative. Displaystyle int x 2 sqrt x 3 1 dx x 2 x 3 1 d x. Make substitutions into the original problem removing all forms of x resulting in. U substitution recall the substitution rule from math 141 see page 241 in the textbook.

Solutions to u substitution solution 1. E x2 2x 3 c. Theorem if u g x is a differentiable function whose range is an interval i and f is continuous on i then ˆ f g x g x dx ˆ f u du. So for our first step we will start with problems where the substitution is given.
Substitute into the original problem replacing all forms of x getting. Note that u substitution with definite integration can be found here in the definite integration section u substitution with exponential and logarithmic integration can be found in the exponential and logarithmic integration section and u substitution with inverse trig functions can be found in the derivatives and integrals of inverse trig functions section. Our mission is to provide a free world class education to anyone anywhere. Of course it is the same answer that we got before using the chain rule backwards.
