acosh()
acosh(x) returns inverse hyperbolic cosine of x , the input number x is in radian.
import math
print(math.acosh(1)) # 0.0
print(math.acosh(1.5)) # 0.9624236501192069
print(math.acosh(5)) # 2.2924316695611777
Note that all the inputs are in radian.
For any value less than 1 , we will get ValueError
import math
print(math.acosh(0.9))
Above code will generate error.
Inputs in degree
We can convert radian value to degree and use the same
import math
in_degree = 60
in_redian = math.radians(in_degree)
print(math.acosh(in_redian)) # 0.30604210861326536
Output
0.30604210861326536
1 radian = 57.2957914331 degree
1 degree = 0.0174533 radian
Drawing graph of acosh()
We will use Matplotlib to generate graph of acosh
import matplotlib.pyplot as plt
x=[]
y=[]
i=1
while (i<=20):
x.append(i)
y.append(math.acosh(i))
i=i+0.1
plt.plot(x,y)
plt.grid(linestyle='-',
linewidth=0.5,color='#f1f1f1')
plt.show()
