Math question c2 differentiationWatch
I don't understand the question where you have a equation and your expected to find the coordinates or the stationary point out of nothing? Like for example 3 root x - 5x +1, I can differentiate this but I csnt find the coordinates how do I do it? I can't solve it

At stationary points, dy/dx = 0. From there, you rearrange the differential to get the x-coordinate of the stationary point. You sub this value back into the original equation to find the y coordinate of the stationary point.
As you have the x term to the power of (negative) a half, this is the square root. To get rid of a square root, you square both sides to get x^-1 = 100/9
Can you rearrange that to get what x equals?
