To compute the inverse cosine with scimath, use the numpy.emath.arccos() method in Python. Return the “principal value” of the inverse cosine of x. For real x such that abs(x)

To return the result of the power to which the input value is raised with scimath, use the scimath.power() method in Python. Returns x to the power p, i.e. the result of x**p. If x and p are scalars, so is out, otherwise an array is returned.If x contains negative values, the output is converted to the complex domain. The parameter x is the input value. The parameter p is the power(s) to which x is raised. If x contains multiple values, p has to either be a scalar, or contain the same number of values as x. In the ... Read More

To compute the logarithm base 10 with scimath, use the scimath.log10() method in Python Numpy. The method returns the log base 10 of the x value(s). If x was a scalar, so is out, otherwise an array object is returned.For a log10() that returns NAN when real x < 0, use numpy.log10 (note, however, that otherwise numpy.log10 and this log10 are identical, i.e., both return -inf for x = 0, inf for x = inf, and, notably, the complex principle value if x.imag != 0). The 1st parameter, x is the value(s) whose log base 10 is (are) required.StepsAt first, ... Read More

To compute the logarithm base n with scimath, use the scimath.logn() method in Python Numpy. The method returns the log base n of the x value(s). If x was a scalar, so is out, otherwise an array is returned.If x contains negative inputs, the answer is computed and returned in the complex domain. The 1st parameter, n is the integer base(s) in which the log is taken. The 2nd parameter, x is the value(s) whose log base n is (are) required.StepsAt first, import the required libraries −import numpy as npCreating a numpy array using the array() method −arr = np.array([-4, ...

To compute the logarithm base 2 with scimath, use the np.emath.log2() method in Python Numpy. The method returns the log base 2 of the x value(s). If x was a scalar, so is out, otherwise an array is returned. The 1st parameter, x is the value(s) whose log base 2 is (are) required.StepsAt first, import the required libraries −import numpy as npCreating a numpy array using the array() method −arr = np.array([np.inf, -np.inf, 16, np.exp(1), -np.exp(1), -32]) Display the array −print("Our Array...", arr)Check the Dimensions −print("Dimensions of our Array...", arr.ndim) Get the Datatype −print("Datatype of our Array object...", arr.dtype)Get the ...

To compute the square root of input, use the emath.sqrt() method in Python Numpy. The method returns the square root of x. If x was a scalar, so is out, otherwise an array is returned. The parameter x is the input value. For negative input elements, a complex value is returnedStepsAt first, import the required libraries −import numpy as npThe complex input explicity using complex() method −a = complex(-9.0, 0.0) Display the array −print("Display the complex value...", a)To compute the square root of input, use the emath.sqrt() method in Python Numpy −print("Result...", np.emath.sqrt(a)) Exampleimport numpy as np # Explicity ...
