Reference to the trigonometric functions

Summary

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

Function SyntaxDescriptionInput ValuesReturn ValuesMath Notation
sin(<expression>) Sine Radians Ratio of opposite/hypotenuse sides for an angle of Θ radians. sin Θ
cos(<expression>) Cosine Radians Ratio of adjacent/hypotenuse sides for an angle of Θ radians. cos Θ
tan(<expression>) Tangent Radians Ratio of opposite/adjacent sides for an angle of Θ radians. tan Θ
asin(<expression>) 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(<expression>) 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(<expression>) Arctangent
Inverse of tan()
Ratio of sides Radians in the angle for a given ratio of opposite/adjacent sides. atan x
atan2(<y-expression>, <x-expression>) Arctangent
Alternative to atan()
y and x coordinates Radians in the angle for a ratio of y and x coordinates. atan y/x
sinh(<expression>) Hyperbolic sine Number (ex - e-x)/2 sinh x
cosh(<expression>) Hyperbolic cosine Number (ex + e-x)/2 cosh x
tanh(<expression>) Hyperbolic tangent Number (sinh x)/(cosh x) tanh x

Parameters

ParameterDescription
expression 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-expression, x-expression Used in atan2(). Expressions describing values that represent pairs of y and x coordinates.

Description

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

  • If expression is a constant, then the function returns a continuous series.
  • If expression 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.
