Firstky differentiate to gain an equation for the gradient.Differentiating gives:dy/dx = 6x2Insert x = 2 into the above equation to find the gradient at that particular point of the curve.When ...
This question is about turning points of a curve, these occur when the gradient of a line is zero. In its current form, the equation of the curve tells us nothing about the gradient of the curve; it must ...
Integration is the opposite of differentiation.First of all take your 2x3 So in differentiation you would times the power by the coefficient and then minus one from the power.This would give,6x...
The chain rule is used to differentiate when there is a function within another function. For example y=(4x+6)0.5, y=(x+1)3The general formula for the chain rule is dy/dx= dy/d...
First the student needs to differentiate the function to find dy/dx = 2x-6At dy/dx = 0, we know the curve is stationary. Now we can work out the x value such that x = 3Put x=3 back into the original equat...
