Python – math.asinh()函数

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

下面的例子说明了上述函数的使用:

示例 1:

# Python code to implement
# the asinh()function
         
# importing "math"
# for mathematical operations  
import math  
         
# Return the hyperbolic arc sine value of numbers 
print (math.asinh(17))
print (math.asinh(5.6))
print (math.asinh(245))
print (math.asinh(-3445))

输出:

3.5272244561999657
2.4237920435875173
6.194409556009931
-8.837826385072708

示例 2:

# Python code to implement
# the aasinh()function
import math 
import matplotlib.pyplot as plt  
    
in_array = [-0.14159265, -0.57039399, -0.28559933, 
            0.28559933, 0.57039399,  0.94159265] 
    
out_array = [] 
    
for i in range(len(in_array)): 
    out_array.append(math.asinh(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.asinh()")  
plt.xlabel("X")  
plt.ylabel("Y")  
plt.show()  

输出:

Input_Array : 
 [-0.14159265, -0.57039399, -0.28559933, 0.28559933, 0.57039399, 0.94159265]

Output_Array : 
 [-0.14112374861052449, -0.5432727660031201, -0.28185270483975433, 0.28185270483975433, 0.5432727660031201, 0.8394645626112472]
