cot

cot is useful when you work with angular or cyclic calculations and need the cotangent as part of a larger formula. In observability, you might use it to transform normalized metric ratios into angular coordinates for signal analysis.

Usage#

Syntax#

cot(x)

Parameters#

Name	Type	Required	Description
`x`	real	Yes	The angle in radians. Must not be a multiple of π.

Returns#

The cotangent of x. Returns infinity or null when sin(x) equals zero (that is, when x is a multiple of π).

Example#

Use cot to compute the cotangent of an angle in radians.

Query

print result = cot(pi() / 4)

Output

result
1.0000

tan: Returns the tangent, the reciprocal of cot. Use it as the primary trigonometric ratio when cotangent isn't needed.
sin: Returns the sine. Use it along with cos to compute cotangent manually as cos(x)/sin(x).
cos: Returns the cosine. Use it in combination with sin for manual cotangent calculation.
atan: Returns the arc tangent. Use it as the inverse of tan when you need to recover an angle.
radians: Converts degrees to radians. Use it to prepare degree-based angle inputs before calling cot.

Other query languages#

Splunk SPL users

Splunk SPL doesn't include a built-in cot() function. You compute it as the reciprocal of tan().

Splunk example

| eval cot_val = 1 / tan(angle_rad)

APL equivalent

['sample-http-logs']
| extend cot_val = cot(angle_rad)

ANSI SQL users

ANSI SQL does not define a standard COT() function, though SQL Server provides one. In PostgreSQL and other databases, you compute it as 1 / TAN(x).

SQL example

SELECT 1.0 / TAN(angle_rad) AS cot_val FROM logs
