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 mathimport numpy as npimport 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() |
