The cosh() is an inbuilt function in Ruby returns the hyperbolic cosine of value given in radians. The value passed is in range [-inf, +inf]. The returned value is in range [1, +inf].
Syntax: Math.cosh(value)
Parameters: The function accepts one mandatory parameter value whose corresponding hyperbolic cosine value is returned.
Return Value: It returns the hyperbolic cosine value.
Example 1:
CPP
# Ruby program for cosh() function # Assigning values val1 = 0 val2 = 0.67 val3 = 1 val4 = 2 # Prints the cosh() value puts Math. cosh (val1)
puts Math. cosh (val2)
puts Math. cosh (val3)
puts Math. cosh (val4)

Output:
1.0 1.232972949211241 1.5430806348152437 3.7621956910836314
Example 2:
CPP
# Ruby program for cosh() function # Assigning values val1 = 131 val2 = -0.9 val3 = -98 val4 = -767 # Prints the cosh() value puts Math. cosh (val1)
puts Math. cosh (val2)
puts Math. cosh (val3)
puts Math. cosh (val4)
