degrees
Converts degrees to radians.
Syntax

degrees(x)

x
is a real or complex number

Description
This function performs the mapping x ↦ x⋅π/180
, thus converting its argument from degrees to radians.
Notes
This is the function behind the postfix operator °. Typically you use the operator instead of calling the degrees
function directly.
Examples
