Values of other integrals follow by use of the identity-. dJ ν ( x ) = Jν − 1 ( x ) − Jν + 1 ( x ) dx 2. which follows by a simple differentiation with respect to x of the integral form of the Bessel function definition given above. In addition one can establish the identities--. − ν ( x ) = ( − 1 ) ν Jν ( x )

1 Evaluating an integral with a branch cut This is an elementary illustration of an integration involving a branch cut. It may be done also by other means, so the purpose of the example is only to show the method. The integral is Z 1 0 1 p x(1−x) dx = π. The essential point is to consider an appropriate analytic function. The

The solutions can be found by algebra or using the calculator. By the method of washers, the integrand is π (6 2 − ( f (x) + 2. because the outer radius of the washer centered at (x, 0) is 4 + 2 = 6 and the inner radius of that washer is f (x) + 2. Students were expected to evaluate the resulting integral by using the calculator.

Integration by substitution. mc-TY-intbysub-2009-1. There are occasions when it is possible to perform an apparently difficult piece of integration by first making a substitution. This has the effect of changing the variable and the integrand. When dealing with definite integrals, the limits of integration can also change.

So the integral Z 2x √ 1+x2dx is of the form Z f(g(x))g′(x)dx To perform the integration we used the substitution u = 1 + x2. In the general case it will be appropriate to try substituting u = g(x). Then du = du dx dx = g′(x)dx. Once the substitution was made the resulting integral became Z √ udu.

Z 2x cos(x2) dx. Let u = x2, then du/dx = 2x or du = 2x dx. Since we have exactly 2x dx in the original integral, we can replace it by du: Z 2x cos(x2) dx = Z cos u du = sin u + C = sin(x2) + C. This is not the only way to do the algebra, and typically there are many paths to the correct answer.
