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.
