Partial derivatives play a crucial role in the realm of multivariable calculus. They analyze how a multivariable function behaves when one of its variables changes while the others remain constant.

x = np.linspace(0, 2*np.pi, nx, endpoint=True) # X-points y = np.linspace(0, 2*np.pi, ny, endpoint=True) # Y-points dzdx = np.cos(X)*np.sin(Y) # partial derivative (x ...
