Tan Function - Python Math Module

Method name:


Method overview:

The python, math.tan() function returns the ratio of the cosine theta 
value to the sine theta value, for the given radian value.


aRadians_in : Radians for which the tangent θ value needs to be found.

Return value:

The tangent θ value for the given radian value is returned.



# Find tan θ value for common angles

import math


# tan θ value for zero degrees

Radians0    = math.radians(0)

tan0        = math.tan(Radians0)

tan0Rounded = round(tan0,2)


# tan 30 value for zero degrees

Radians30           = math.radians(30)

tan30               = math.tan(Radians30)

tan30Rounded        = round(tan30,2)


# tan 45 value for zero degrees

Radians45       = math.radians(45)

tan45           = math.tan(Radians45)

tan45Rounded    = round(tan45,2)


# tan 60 value for zero degrees

Radians60           = math.radians(60)

tan60               = math.tan(Radians60)

tan60Rounded        = round(tan60,2)


# tan 90 value for zero degrees

Radians90       = math.radians(90)

tan90           = math.tan(Radians90)

tan90Rounded    = round(tan90,2)


# math.tan(radians) : Python Example: Printing tangent θ values for common angles

print("tan 0:{}".format(tan0Rounded))

print("tan 30:{}".format(tan30Rounded))

print("tan 45:{}".format(tan45Rounded))

print("tan 60:{}".format(tan60Rounded))

print("tan 90:{}".format(tan90Rounded))



tan 0:0.0

tan 30:0.58

tan 45:1.0

tan 60:1.73

tan 90:1.633123935319537e+16
