Squared this is called the second derivative.
What is 2nd order partial derivative?
The partial derivative of a function of n variables, is itself a function of n variables. By taking the partial derivatives of the partial derivatives, we compute the higher-order derivatives.
What does the second partial derivative tell you?
The unmixed second-order partial derivatives, f x x and , f y y , tell us about the concavity of the traces. The mixed second-order partial derivatives, f x y and , f y x , tell us how the graph of twists.

What is the significance of second order derivative?
However, it is important to understand its significance with respect to a function. Similarly, as the First Order Derivative at a point gives us the slope of the tangent at that point or the instantaneous rate of change of the function at that point, the Second Order Derivatives are used to get an idea of the shape of the graph of a given function.
What is second order derivative?
The second derivative, or second order derivative, is the derivative of the derivative of a function.
How to take partial derivative?
1) Find the first partial derivatives. With respect to x (holding y constant): f x = 2xy 3 With respect to y (holding x constant): f y = 3x 2) Find the second order derivatives. There are four: f xx = 2y 3 f xy = 6xy 2 f yx = 6xy 2 f xx = 6x 2 3) Identify the mixed partial derivatives. There are two:
What is dy dx?
The problem is that [math]dy/dx[/math] was originally thought of as a quotient representing a small change in the y variable over a small change in the x variable. However, given the introduction of differentiation by first principles, the derivative is no longer defined as this change but rather as a limit:
