WebThe reason for a new type of derivative is that when the input of a function is made up of multiple variables, we want to see how the function changes as we let just one of those variables change while holding all the others constant. With respect to three-dimensional graphs, you can picture the partial derivative. WebThe derivative of a function represents its a rate of change (or the slope at a point on the graph). What is the derivative of zero? The derivative of a constant is equal to zero, hence the derivative of zero is zero. What does the third derivative tell you? The third derivative is the rate at which the second derivative is changing. WebApr 15, 2024 · So, my x and y derivatives are matching (taking derivatives in Fourier space).
