Euler and Legendre Equations (Mathematica Tutorial)

An Euler equation has the general form Euler equations can be solved by transforming them to equations with constant coefficients. This is an example of an Euler equation.

Combine Two or More Graphics (Mathematica How To)

When working with graphics in Mathematica , you may want to combine several graphics into a single image. Mathematica can combine graphics by overlaying them or by embedding ...

Apart (Built-in Mathematica Symbol)

Apart[expr] rewrites a rational expression as a sum of terms with minimal denominators. Apart[expr, var] treats all variables other than var as constants.

Assumptions (Built-in Mathematica Symbol)

Assumptions is an option for functions such as Simplify, Refine, and Integrate that specifies default assumptions to be made about symbolic quantities.

Attributes (Built-in Mathematica Symbol)

Attributes[symbol] gives the list of attributes for a symbol.
