  then the integral becomes Z 2xcos(x2)dx = Z 2xcosu du 2x = Z cosudu. The important thing to remember is that you must eliminate all instances of the original variable x. EXAMPLE8.1.1 Evaluate Z (ax+b)ndx, assuming that a and b are constants, a 6= 0, and n is a positive integer. We let u = ax+ b so du = adx or dx = du/a. Then Z (ax+b)ndx = Z 1 a

  A double integral is something of the form ZZ R f(x,y)dxdy where R is called the region of integration and is a region in the (x,y) plane. The double integral gives us the volume under the surface z = f(x,y), just as a single integral gives the area under a curve. 0.2 Evaluation of double integrals To evaluate a double integral we do it in ...

Hence, the integral becomes: Z 1 p x2 9 dx = Z 1 3tan (3sec tan d ) = Z sec d : This can be integrated directly using a clever trick, but should probably instead be considered an integral you should know.

  A type of integral which brings in some new ideas is similar to Type 2 but with a pole of the integrand actually on the contour of integration. As an example of a situation where this arises, consider the real integral I = +∞ −∞ cosx x dx The approach previously discussed would involve replacing cosx/x by eiz/z,in

  uously distributed random variable X with probability density function f, using the Monte Carlo integration, we notice that E{g(X)} = Z g(x)f(x)dx. This integral is then calculated with the Monte Carlo method. To calculate the probability P{X ∈ O}, for a set O, we make similar use of the fact that P{X ∈ O} = Z IO(x)f(x)dx where IO(x) = (1 ...

We can write these as limits on u using the substitution u = 9+x. Clearly, when x = 1, u = 10, and when x = 3, u = 12. So we require Z u=12
