trans

Syntax

trans(function, transformation, point)

Description

Applies transformation to function. If the transformation results in something that isn't a function then the domain of function is restricted so that the result is a function. point is a value of x that will not be removed from the domain. The independent variable is assumed to be x, and the dependent variable y, because there is no parameter to specify what they are.

Parameters

function
A function in terms of x to be transformed.
transformation
Two equations that define the transformation by relating x_ and y_ to x and y. You may be used to using a prime symbol (e.g. x') instead of an underscore but this is not a valid variable name on the TI-Nspire.

What these equations mean is that for every point (x, y) on the original function, there is a point (x_, y_) on the new function. These equations can be specified in any way that simultaneous equations can be specified on the TI-Nspire.
point
An x value of function that is not to be excluded from the domain. See this parameter's description in inv for further clarification.

Return Value

The transformed function.
