Question : What is gradient ? Write a gradient example Solution : Gradient Gradient is an vector operator that operates on a scalar function and obtained it’s vector differentiation. It is written as \[\nabla\left(\phi\right)=\left(\hat{i}\frac{\partial}{\partial x}+\hat{j}\frac{\partial}{\partial x}+\hat{k}\frac{\partial}{\partial x}\right) \phi \] Gradient…
