The numpy.arcsin() function in Python is used to determine the inverse sine, element-wise, of a given array.
numpy.arcsin(x, /, out=None, *, where=True)
The numpy.arcsin() function takes the following parameter values:
x: This represents the y-coordinate on the unit circle. This parameter value is required for the function to work.out: This represents a location where the result is stored. This is an optional parameter value.where: This is the condition over which the input is broadcast. At a given location where this condition is True, the resulting array will be set to the ufunc result. Otherwise, the resulting array will retain its original value. This is also an optional parameter value.**kwargs: This represents the other keyword arguments.The numpy.arcsin() function returns the inverse sin of each element in a given array in radians and in a closed interval [-pi/2, pi/2].
import numpy as np# creating an arrayx = np.array([[1, 0], [-1, -0.5]])# taking the arcsin element-wisemyarray = np.arcsin(x)print(myarray)
numpy module.x, using the array() method.np.arcsin() function on the array. Then, we assign the result to a variable called myarray.myarray to the console.
