What does D 2y dx 2 mean?
D^2y/dx^2 means 2 time derivative and.
(Dy/DX )^2 means 1 times derivative and square of 1 time derivative.
For example, Let’s take.
Y=x.

What happens when D 2y dx 2?
If d2y/dx2 = 0, you must test the values of dy/dx either side of the stationary point, as before in the stationary points section. When x = 3, d2y/dx2 = 18, which is positive. Hence there is a minimum point at x = 3 and a maximum point at x = -3.
What does D DX mean?
By d/dx we mean there is a function to be differentiated; d/dx of something means that “something” is to be differentiated with respect to x. dy/dx means to “differentiate y with respect to x” as dy/dx means the same thing as d/dx(y).
How do you find second implicit differentiation?
Using Implicit Differentiation to find a Second Derivative –
What does a second derivative tell you?
The second derivative tells us a lot about the qualitative behaviour of the graph. If the second derivative is positive at a point, the graph is concave up. If the second derivative is positive at a critical point, then the critical point is a local minimum. The second derivative will be zero at an inflection point.
Is dy dx 2 the same as D 2y dx 2?
d2y/dx2 is the secondary derivative of y with respect to x , but (dy/dx)^2 is the square of the first order derivative dy/dx. If the question is related to (dydx) then it is meaningless in terms of differentiation.
