LogarithmicFunction(asymval, pt1, pt2)
logarithmic function in a single variable.
x-value for horizontal asymptote
a GridPoint object or list/rtable representing a point on the function
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
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.
<< LogarithmicFunction: 5*ln(2*x-4)/ln(10)+5>>
<< LogarithmicFunction: 1.5/ln(2)*ln(v-2)+6.5>>
L1 ≔ LogarithmicFunction⁡3,4,0,6,ln⁡3,'variable'='z'
L1 ≔ << LogarithmicFunction: ln(z-3)>>
The Grading:-LogarithmicFunction command was introduced in Maple 18.
