Trigonometric tangent is equivalent to np.sin(x)/np.cos(x) element-wise. To find the Trigonometric tangent of an angle, use the numpy.tan() method in Python Numpy. The method returns the sine of each element of the 1st parameter x. This is a scalar if is a scalar. The 1st parameter, x, is an Angle, ... Read More

To compute the condition number of a matrix in linear algebra, use the numpy.linalg.cond() method in Python. This method is capable of returning the condition number using one of seven different norms, depending on the value of p. Returns the condition number of the matrix. May be infinite.The condition number ... Read More

The arcsin is a multivalued function: for each x there are infinitely many numbers z such that sin(z) = x. The convention is to return the angle z whose real part lies in [-pi/2, pi/2]. The inverse sine is also known as asin or sin^{-1}.For real-valued input data types, arcsin ... Read More

To return the imaginary part of the complex argument, use the numpy.imag() method. The method returns the imaginary component of the complex argument. If val is real, the type of val is used for the output. If val has complex elements, the returned type is float. The 1st parameter, val ... Read More

The numpy.promote_types() method returns the data type with the smallest size and smallest scalar kind to which both type1 and type2 may be safely cast. Returns the promoted data type. The returned data type is always in native byte order. The 1st parameter is the first data type. The 2nd ... Read More

The numpy.can_cast() method returns True if cast between data types can occur according to the casting rule. The 1st parameter is the data type or array to cast from. The 2nd parameter is the data type to cast to. The 3rd parameter controls what kind of data casting may occur, ... Read More

To return the cumulative sum of array elements over a given axis treating NaNs as zero, use the nancumprod() method. The cumulative sum does not change when NaNs are encountered and leading NaNs are replaced by zeros.Zeros are returned for slices that are all-NaN or empty. The method returns a ... Read More

The arcsin is a multivalued function: for each x there are infinitely many numbers z such that sin(z) = x. The convention is to return the angle z whose real part lies in [-pi/2, pi/2]. For real-valued input data types, arcsin always returns real output. For each value that cannot ... Read More

Trigonometric tangent is equivalent to np.sin(x)/np.cos(x) element-wise. To get the Trigonometric tangent of an array of angles given in degrees, use the numpy.tan() method in Python Numpy. The method returns the tangent of each element of the 1st parameter x. The 1st parameter, x, is an Angle, in radians (2pi ... Read More

The gradient is computed using second order accurate central differences in the interior points and either first or second order accurate one-sides (forward or backwards) differences at the boundaries. The returned gradient hence has the same shape as the input array. The 1st parameter, f is an Ndimensional array containing ... Read More
