Python | math.tan() function

In Python, math module contains a number of mathematical operations, which can be performed with ease using the module. math.tan() function returns the tangent of value passed as argument. The value passed in this function should be in radians.

Syntax: math.tan(x)

Parameter:
x : value to be passed to tan()

Returns: Returns the tangent of value passed as argument

Code #1:




# Python code to demonstrate the working of tan()
     
# importing "math" for mathematical operations 
import math 
    
a = math.pi / 6
     
# returning the value of tangent of pi / 6 
print ("The value of tangent of pi / 6 is : ", end ="") 
print (math.tan(a)) 


 
Code #2:




# Python program showing 
# Graphical representation of 
# tan() function 
import math
import numpy as np
import matplotlib.pyplot as plt 
  
in_array = np.linspace(0, np.pi, 10
  
out_array = []
  
for i in range(len(in_array)):
    out_array.append(math.tan(in_array[i]))
    i += 1
  
   
print("in_array : ", in_array) 
print("\nout_array : ", out_array) 
  
# red for numpy.sin() 
plt.plot(in_array, out_array, color = 'red', marker = "o"
plt.title("math.tan()"
plt.xlabel("X"
plt.ylabel("Y"
plt.show() 


Output:

in_array : [0. 0.34906585 0.6981317 1.04719755 1.3962634 1.74532925
2.0943951 2.44346095 2.7925268 3.14159265]

out_array : [0.0, 0.36397023426620234, 0.8390996311772799, 1.7320508075688767, 5.671281819617707, -5.671281819617711, -1.7320508075688783, -0.8390996311772804, -0.36397023426620256, -1.2246467991473532e-16]
