Quaternions Package (Quaternions Package Tutorial)

This package implements Hamilton's quaternion algebra. Quaternions have the form a+bi+cj+dk where a, b, c, and d are real numbers. The symbols i, j, and k are multiplied ...

ArcCsc (Built-in Mathematica Symbol)

ArcCsc[z] gives the arc cosecant csc -1 (z) of the complex number z.

ArcSec (Built-in Mathematica Symbol)

ArcSec[z] gives the arc secant sec -1 (z) of the complex number z.

CountRoots (Built-in Mathematica Symbol)

CountRoots[poly, x] gives the number of real roots of the polynomial poly in x.CountRoots[poly, {x, a, b}] gives the number of roots between a and b.

DifferentialRootReduce (Built-in Mathematica Symbol)

DifferentialRootReduce[expr, x] attempts to reduce expr to a single DifferentialRoot object as a function of x.DifferentialRootReduce[expr, {x, x_0}] takes the initial ...

Sqrt (Built-in Mathematica Symbol)

Sqrt[z] or Sqrt[z] gives the square root of z.

TeXForm (Built-in Mathematica Symbol)

TeXForm[expr] prints as a TeX version of expr.
