Python3 tan () function
description
tan () returns the sine of x radians.
grammar
The following is the syntax tan () method:
import math math.tan(x)
Note: tan () is not directly accessible, you need to import math module, and then call the method by math static objects.
parameter
- x - a value.
return value
Returns the sine of x in radians, values between -1 and 1.
Examples
The following illustrates the use of tan () method Example:
#!/usr/bin/python3
import math
print ("(tan(3) : ", math.tan(3))
print ("tan(-3) : ", math.tan(-3))
print ("tan(0) : ", math.tan(0))
print ("tan(math.pi) : ", math.tan(math.pi))
print ("tan(math.pi/2) : ", math.tan(math.pi/2))
print ("tan(math.pi/4) : ", math.tan(math.pi/4))
After running the above example output is:
(tan(3) : -0.1425465430742778 tan(-3) : 0.1425465430742778 tan(0) : 0.0 tan(math.pi) : -1.2246467991473532e-16 tan(math.pi/2) : 1.633123935319537e+16 tan(math.pi/4) : 0.9999999999999999
