Gradient is a measure of how steep a slope is. The greater the gradient the steeper a slope is. The smaller the gradient the shallower a slope is. Gradient is usually expressed as a simplified ...

It is well known how to expand in spherical harmonics the gradient of a radial function in turn multiplied by a spherical harmonic. This expansion involves the use of the Wigner–Eckart theorem for the ...

Any straight line graph has a constant gradient, which is calculated by the change in 𝑦 divided by the change in 𝑥, along any section of the graph. The gradient is measuring the steepness of the ...
