Getting inverse cosine and inverse hyperbolic cosine in Julia – acos(), acosh() and acosd() Methods

The acos() is an inbuilt function in julia which is used to calculate inverse cosine of the specified value and output is in radians.

Syntax: acos(x)

Parameters:

• x: Specified values.

Returns: It returns the calculated inverse cosine of the specified value and output is in radians.

Example:

# Julia program to illustrate
# the use of acos() method

# Getting inverse cosine of the specified
# values and output is in radians.
println(acos(0))
println(acos(-0.444))
println(acos(0.7774))
println(acos(1))

Output:

1.5707963267948966
2.0308542405657466
0.6802746363624282

The acosh() is an inbuilt function in julia which is used to calculate inverse hyperbolic cosine of the specified value.

Syntax: acosh(x)

Parameters:

• x: Specified values.

Returns: It returns the calculated inverse hyperbolic cosine of the specified value.

Example:

# Julia program to illustrate
# the use of acosh() method

# Getting inverse hyperbolic cosine of the
# specified values.
println(acosh(2))
println(acosh(10))
println(acosh(74))
println(acosh(45))

Output:

1.3169578969248166
2.993222846126381
4.997166616875528
4.499686190671499

The acosd() is an inbuilt function in julia which is used to calculate inverse cosine of the specified value and output is in degrees.

Syntax: acosd(x)

Parameters:

• x: Specified values.

Returns: It returns the calculated inverse cosine of the specified value and output is in degrees.

Example:

# Julia program to illustrate
# the use of acosd() method

# Getting inverse cosine of the specified
# values and output is in degrees.
println(acosd(0))
println(acosd(-0.444))
println(acosd(0.7774))
println(acosd(1))

Output:
