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:
import math
a = math.pi / 6
print ( "The value of tangent of pi / 6 is : " , end = "")
print (math.tan(a))
|
Code #2:
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)
plt.plot(in_array, out_array, color = 'red' , marker = "o" )
plt.title( "math.tan()" )
plt.xlabel( "X" )
plt.ylabel( "Y" )
plt.show()

Output:
