"Defining Variables" discussed assignments such as x=y which set x equal to y. Here we discuss equations, which test equality. The equation x==y tests whether x is equal to ...

The Mathematica function Integrate[f,x] gives you the indefinite integral ∫f dx. You can think of the operation of indefinite integration as being an inverse of ...

Mathematica allows you to perform many operations on power series. In all cases, Mathematica gives results only to as many terms as can be justified from the accuracy of your ...

This constructs the sum ∑_(i=1)^7 (x^i)/(i) . You can leave out the lower limit if it is equal to 1. This makes i increase in steps of 2, so that only odd-numbered values are ...

Mathematica notebooks consist of sequences of cells. The hierarchy of cells serves as a structure for organizing the information in a notebook, as well as specifying the ...

ReturnAsJavaObject[expr] causes a Java method call or field access during the evaluation of expr to return its result as an object reference (a JavaObject expression), not a ...

MakeNETObject[expr] constructs a .NET object that represents the given Mathematica expression. MakeNETObject[expr, type] creates an object of the specified type from expr.

ReturnAsNETObject[expr] causes a .NET call during the evaluation of expr to return its result as an object reference (i.e., a NETObject expression), not a value.

int MLGetReal (MLINK link, double *x) gets a floating-point number from the MathLink connection specified by link and stores it in x.
