What is Math.tan() in Scala?
The tan() function returns the tangent of a number in radians.
The following illustration shows the mathematical representation of the tan() function.
The
scala.math._header file is required for this function.
This
tan()function only works for right-angled triangles.
Syntax
def tan(x: Double): Double
Parameter
This function requires a number that represents an angle in radians as a parameter.
To convert
degreestoradians, you can use the following formula.
radians = degrees * ( Pi / 180 )
Return value
tan() returns the tangent of a number in radians that is sent as a parameter.
If the parameter value is
NaNorPositiveInfinityorNegativeInfinity, then it returnsNaN.
Code
import scala.math._object Main extends App {//positive number in radiansprintln(s"The value of tan(2.3) = ${tan(2.3)}");// negative number in radiansprintln(s"The value of tan(-2.3) = ${tan(-2.3)}");//converting the degrees angle into radians and then applying tan()// degrees = 45.0// PI = 3.14159265// result first converts degrees to radians then apply tanprintln(s"The value of tan(45.0) = ${tan(45.0 * (Pi / 180.0))}");//error outputsprintln(s"The value of tan(Double.PositiveInfinity) = ${tan(Double.PositiveInfinity)}");println(s"The value of tan(Double.NegativeInfinity) = ${tan(Double.NegativeInfinity)}");println(s"The value of tan(Double.NaN) = ${tan(Double.NaN)}");}
