Trigonometric Functions

Reference to the trigonometric functions

Summary

Performs the indicated trigonometric function on each data value described by tsExpression.

Function Syntax	Description	Input Values	Return Values	Math Notation
`sin(<tsExpression>)`	Sine	Radians	Ratio of opposite/hypotenuse sides for an angle of Θ radians.	`sin` Θ
`cos(<tsExpression>)`	Cosine	Radians	Ratio of adjacent/hypotenuse sides for an angle of Θ radians.	`cos` Θ
`tan(<tsExpression>)`	Tangent	Radians	Ratio of opposite/adjacent sides for an angle of Θ radians.	`tan` Θ
`asin(<tsExpression>)`	Arcsine Inverse of `sin()`	Ratio of sides. Number -1 < x < 1	Radians in the angle for a given ratio of opposite/hypotenuse sides.	`asin` `x`
`acos(<tsExpression>)`	Arccosine Inverse of `cos()`	Ratio of sides. Number -1 < x < 1	Radians in the angle for a given ratio of adjacent/hypotenuse sides.	`acos` `x`
`atan(<tsExpression>)`	Arctangent Inverse of `tan()`	Ratio of sides	Radians in the angle for a given ratio of opposite/adjacent sides.	`atan` `x`
`atan2(<y-tsExpression>, <x-tsExpression>)`	Arctangent Alternative to `atan()`	y and x coordinates	Radians in the angle for a ratio of y and x coordinates.	`atan` `y``/``x`
`sinh(<tsExpression>)`	Hyperbolic sine	Number	(e^x - e^-x)/2	`sinh` `x`
`cosh(<tsExpression>)`	Hyperbolic cosine	Number	(e^x + e^-x)/2	`cosh` `x`
`tanh(<tsExpression>)`	Hyperbolic tangent	Number	(`sinh` `x`)/(`cosh` `x`)	`tanh` `x`

Parameter	Description
tsExpression	Expression describing input values that are interpreted as indicated in the table above. Note: You can use `toRadians()` to convert values from numbers of degrees to numbers of radians.
y-tsExpression, x-tsExpression	Used in `atan2()`. Expressions describing values that represent pairs of y and x coordinates.

Each trigonometric function produces data points by performing a calculation on the data points returned by the input expression.

If tsExpression is a constant, then the function returns a continuous series.
If tsExpression describes one or more time series, then the function returns a new time series for each input time series. Each value in a new time series is obtained by operating on the value of the corresponding point in the input time series.
