Using the math functions

The Math list contains the following functions:

Function Abbreviation Description

Square Root Sqrt(x) Returns the square root of x

Natural logarithm Ln(x) Returns the natural logarithm of x

Exponential Exp(x) Returns the exponential (inverse of the

natural logarithm) of x

Gamma Gamma(x) Returns the gamma of x (Factorial(x – 1) for

positive integers)

Logarithm Log(x) Returns the logarithm of x, base 10

Modulus Mod(x,y) Returns the modulus of x with respect to y

(that is, the remainder of x/y)

Remainder Remainder(x,y) Returns x – y * round(x/y)

Factorial Factorial(x) Returns the factorial of x

Using the Remainder function

The Remainder function is not simply the remainder of x/y (the modulus function is).

The Remainder function returns x – y * round(x/y). A different definition is

x – remainder(x,y), which gives the closest value to x that is evenly divisible by y.

Examples

y(x) = 0.5*ln((1+x)/(1–x))

y(x) = 1/sqrt(4*x^2+1)

y(x) = exp(x)/(1–exp(2*x))
