LowerTriangularize[m] gives a matrix in which all but the lower triangular elements of m are replaced with zeros. LowerTriangularize[m, k] replaces with zeros only the ...

LogIntegral[z] is the logarithmic integral function li(z).

ArithmeticGeometricMean[a, b] gives the arithmetic-geometric mean of a and b.

Power series are in many ways the algebraic analog of limited-precision numbers. Mathematica can generate series approximations to virtually any combination of built-in ...

Thickness[r] is a graphics directive which specifies that lines which follow are to be drawn with thickness r. The thickness r is given as a fraction of the horizontal plot ...

Built on powerful and elegant long-standing principles, the core Mathematica language has been gradually enhanced under tight control over its twenty-year history. Version ...

HankelH1[n, z] gives the Hankel function of the first kind H_n^(1)(z).

HankelH2[n, z] gives the Hankel function of the second kind H_n^(2)(z).

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 ...
