arccos() - ( NumPy Functions )

Heading h2

Syntax

numpy.arccos(x, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj])

Example

import numpy as np

x = np.cos(np.array([0, np.pi/2, np.pi]))
y = np.arccos(x)
print(y)

Output

[1.57079633 1.57079633 0.        ]

Explanation

The arccos() function in NumPy is used to calculate inverse cosine of a given value. It accepts a value, x, as a parameter and returns the corresponding inverse cosine value in radians. The input values must be in the range [-1, 1].

Use

The arccos() function is used to calculate the inverse cosine of a given value, which is useful in various mathematical calculations, such as in trigonometry and geometry. It can also be useful in data analysis and data science applications.

Important Points

• The arccos() function in NumPy is used to calculate inverse cosine of a given value.
• The input values must be in the range [-1, 1].
• The output values of arccos() are in radians.

Summary

In conclusion, the arccos() function in NumPy is used to calculate the inverse cosine of a given value. It accepts a value, x, as a parameter and returns the corresponding inverse cosine value in radians. The input values must be in the range [-1, 1]. The function is useful in various mathematical calculations, such as in trigonometry and geometry. It can also be useful in data analysis and data science applications.
