and I need to find the stationary points of the function. I understand that I need to work out the partial derivative with respect to x, and then equate this term to zero, and then to find which values of x and y this is valid for (i.e. finding the x and y point at which the gradient is zero)

26.03.2015 · For two-variables function, critical points are defined as the points in which the gradient equals zero, just like you had a critical point for the single-variable function f(x) if the derivative f'(x)=0. The matter is that you now can differentiate the function with respect to more than one variable (namely 2, in your case), and so you must define a derivative for each directions.

Method: finding stationary points. Given a function f ( x) and its curve y = f ( x), to find any stationary point (s) we follow three steps : Step 1: find f ′ ( x) Step 2: solve the equation f ′ ( x) = 0, this will give us the x -coordinate (s) of any stationary point (s) . Step 3 (if needed/asked): calculate the y -coordinate (s) of the ...

Stationary points, aka critical points, of a curve are points at which its derivative is equal to zero, 0. Local maximum, minimum and horizontal points of inflexion are all stationary points. We learn how to find stationary points as well as determine their natire, maximum, minimum or horizontal point of inflexion. The tangent to the curve is horizontal at a stationary point, since its ...

Jun 26, 2018 · As we can see from this image, a stationary point is a point on a curve where the slop is zero. Hence the stationary points are when the derivative is zero. Hence to find the stationary point of y = f (x) , find dy dx and then set it equal to zero. ⇒ dy dx = 0. Then solve this equation, to find the values of x for what the function is stationary.
