What is sinh() in R?
The sinh() function returns the hyperbolic sine of a number in radians.
The illustration below shows the mathematical representation of the sinh() function.
Syntax
sinh(num)
Parameter
This function requires a number that represents an angle in radians as a parameter.
The following formula is used to convert degrees to radians.
radians = degrees * ( pi / 180.0 )
Return value
sinh() returns a number’s hyperbolic sine (in radians), which is sent as a parameter.
-
If the value of
numis positive infinity, then the value returned ispositive infinity. -
If the value of
numis negative infinity, then the value returned isnegative infinity. -
If the value of
numisNaN not a number NaN.
