Octave Built-In Functions

Description

Octave has many built-in functions such as sin(x), exp(x), and log(x). Note that the natural logarithm command is {log(x)}} and not ln(x). A list of built-in functions for Octave is given below.

Math Notation Octave Command Math Notation Octave Command
$\sqrt{x}$ sqrt(x) $e^x$ exp(x)
$\ln{x}$ log(x) $\log_{10}{x}$ log10(x)
$\cos{x}$ cos(x) $\sin{x}$ sin(x)
$\tan{x}$ tan(x) $\cot{x}$ cot(x)
$\sec{x}$ sec(x) $\csc{x}$ csc(x)
$\cos^{-1}{x}$ acos(x) $\sin^{-1}{x}$ asin(x)
$\tan^{-1}{x}$ atan(x) $\cot^{-1}{x}$ acot(x)
$\sec^{-1}{x}$ asec(x) $\csc^{-1}{x}$ acsc(x)
$\cosh{x}$ cosh(x) $\sinh{x}$ sinh(x)
$\tanh{x}$ tanh(x) $\coth{x}$ coth(x)
$\text{sech}{x}$ sech(x) $\text{csch}{x}$ csch(x)
$\cosh^{-1}{x}$ acosh(x) $\sinh^{-1}{x}$ asinh(x)
$\tanh^{-1}{x}$ atanh(x) $\coth^{-1}{x}$ acoth(x)
$\text{sech}^{-1}{x}$ asech(x) $\text{csch}^{-1}{x}$ acsch(x)
