The numpy.sinh() is a mathematical function that helps user to calculate hyperbolic sine for all x(being the array elements).
Equivalent to 1/2 * (np.exp(x) – np.exp(-x)) or -1j * np.sin(1j*x).
Syntax: numpy.sinh(x[, out]) = ufunc ‘sin’)
Parameters :array : [array_like] elements are in radians.
2pi Radians = 36o degreesReturn : An array with hyperbolic sine of x for all x i.e. array elements
Code #1 : Working
# Python3 program explaining # sinh() function import numpy as np
import math
in_array = [ 0 , math.pi / 2 , np.pi / 3 , np.pi]
print ( "Input array : \n" , in_array)
Sinh_Values = np.sinh(in_array)
print ( "\nSine Hyperbolic values : \n" , Sinh_Values)

Output :
Input array : [0, 1.5707963267948966, 1.0471975511965976, 3.141592653589793] Sine Hyperbolic values : [ 0. 2.3012989 1.24936705 11.54873936]
Code #2 : Graphical representation
# Python program showing Graphical # representation of sinh() function import numpy as np
import matplotlib.pyplot as plt
in_array = np.linspace( - np.pi, np.pi, 12 )
out_array = np.sinh(in_array)
print ( "in_array : " , in_array)
print ( "\nout_array : " , out_array)
# red for numpy.sinh() plt.plot(in_array, out_array, color = 'red' , marker = "o" )
plt.title( "numpy.sinh()" )
plt.xlabel( "X" )
plt.ylabel( "Y" )
plt.show() |
Output :
