Python math.sinh()用法及代码示例

数学模块包含许多用于数学运算的函数。 math.sinh()函数返回数字的双曲正弦值。

用法： math.sinh(x)

以下示例说明了上述函数的用法：

范例1：

# Python code to implement 
# the sinh()function 
        
# importing "math" 
# for mathematical operations   
import math   
       
a = math.pi / 6
        
# Return the hyperbolic cosine value of numbers  
print (math.sinh(7)) 
print (math.sinh(56)) 
print (math.sinh(2.45)) 
print (math.sinh(1))

输出：

548.3161232732465
1.045829748006498e+24
5.75102656636201
1.1752011936438014

范例2：

# Python code implementation of  
# the sinh() function 
import math  
import numpy as np  
import matplotlib.pyplot as plt   
     
in_array = np.linspace(1, np.pi**2, 30)  
     
out_array = []  
     
for i in range(len(in_array)):  
    out_array.append(math.sinh(in_array[i]))  
    i += 1
      
print("Input_Array:\n", in_array)   
print("\nOutput_Array:\n", out_array)   
   
   
plt.plot(in_array, out_array, "go-")   
plt.title("math.sinh()")   
plt.xlabel("X")   
plt.ylabel("Y")   
plt.show()
