Ruby - Math.tan() Method



The Ruby Math.tan() method returns trigonometric tangent of an angle (angle should be in radians). The return type of this method is float.

In the graph below, tan(x) vs x is plotted.

Tan Function

Syntax

Math.tan(x)

Parameters

x Specify the angle in radian.

Return Value

Returns the trigonometric tangent of an angle.

Example:

In the example below, Math.tan() method is used to find out the trigonometric tangent of an angle.

#Math::PI - value of PI from Math module
pi = Math::PI

puts "Math.tan(pi/6) = #{Math.tan(pi/6)}"
puts "Math.tan(pi/4) = #{Math.tan(pi/4)}"
puts "Math.tan(pi/3) = #{Math.tan(pi/3)}"

The output of the above code will be:

Math.tan(pi/6) = 0.5773502691896257
Math.tan(pi/4) = 0.9999999999999999
Math.tan(pi/3) = 1.7320508075688767
