Calling Sequence

LogarithmicFunction(f)

LogarithmicFunction(asymval, pt1, pt2)

Parameters

f

-

logarithmic function in a single variable.

asymval

-

x-value for horizontal asymptote

pt1, pt2

-

a GridPoint object or list/rtable representing a point on the function

Options

• 

domain : a RealRange expression specifying the region over which the function is defined

• 

variable: name used in generated expression when second calling sequence is used

Description

• 

The LogarithmicFunction constructor generates and returns an object representing a logarithmic function. The function is assumed to have the form aln(bx+c)+d, where a, b, c and d are constants. Logarithms in different bases using the log[b] notation are supported.

• 

The first calling sequence requires a logarithmic function in one variable to be provided.

• 

The second calling sequence requires the value for the vertical asymptote and two points on the curve to be provided.
