Python math.acosh() method is “used to calculate the hyperbolic arc cosine of the given number in radians”.
Syntax
math.acosh(var)
Here, var is the variable of which hyperbolic cosine arc we must find.
Parameters
var: It is a positive number >= 1. If x is not a number, it returns a TypeError.
Return Value
It returns the hyperbolic arc cosine value of the number in the float datatype.
Example 1: How to Use the math.acosh() Method
import math
a1 = 3.5
b1 = 1
c1 = 7
d1 = 5.3
print("Value for parameter ", a1, " is ", math.acosh(a1))
print("Value for parameter ", b1, " is ", math.acosh(b1))
print("Value for parameter ", c1, " is ", math.acosh(c1))
print("Value for parameter ", d1, " is ", math.acosh(d1))Output
Value for parameter 3.5 is 1.9248473002384139
Value for parameter 1 is 0.0
Value for parameter 7 is 2.6339157938496336
Value for parameter 5.3 is 2.351832816454804Example 2: ValueError: math domain error
import math
q = 0.5
print(math.acosh(q))Output
ValueError: math domain error
In this example, we’ve seen that we get a math domain error by passing a parameter that is less than 1.
That’s it.
