But the numerical integration works very nicely, except that over a certain limited range and size of variable these pesky imaginary components spring up. Integrate does not do integrals the way people do. It calls Mathematica's Integrate function, which represents a huge amount of mathematical and computational research. Hands-on Start to Wolfram Mathematica This tutorial helps you get started with Mathematicalearn how to create your first notebook, run calculations, generate visualizations, create interactive models, analyze data, and more. WolframAlpha computes integrals differently than people. If, on the other hand, you need to do it in spherical or cylindrical coordinates, then you have to add in a few more factors, which I could explain if you need them. My integrals are similar to Elliptical integrals, but there are additional terms in the denominator of the integrand function that make an analytical solution impossible. WolframAlpha can solve a broad range of integrals. Where you have to supply the forms for f(x,y,z) and g(x,y,z). Integrate can give results in terms of many special functions. It can also evaluate integrals that involve exponential, logarithmic, trigonometric, and inverse trigonometric functions, so long as the result comes out in terms of the same set of functions. If you use Cartesian (the simplest) thenĪnd now how you have to do a triple integral (one integral for dx where you think of y and z as constants, one for dy where you think of x and z and constants, and similarly for dz). Compute answers using Wolframs breakthrough technology & knowledgebase, relied on by millions of students & professionals. Integrate can evaluate integrals of rational functions. It means that you want to integrate over all space, so first you need to pick a set of coordinates (which will probably depend on the coordinates in which you have f(x) and g(x) expressed).
