cotangent function
The cot
function is a trigonometric function. The cot
function returns the cotangent of an angle specified in radians.
Syntax:
double cot(n)
Semantics:
- n: The argument n is an expression that resolves to a number (an angle expressed in radians).
- return type: double.
- Returns a NULL value in the following cases:
- n resolves to a NULL value
- n does not resolve to a number
- Returns NaN if n resolves to NaN or infinity(positive/negative).
- Returns a NULL value in the following cases:
