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...

Beaucoup de français font encore cette faute d'orthographe. Savoir quelle forme choisir peut être difficile mais apprendre à faire la différence entre les deux formes est fondamentale étant donné que les ...

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...

cos(2y)= (cos(y))^2 - (sin(y))^2 identitynow consider identity (cos(y))^2+(sin(y))^2=1by rearranging this to (cos(y))^2 - 1 = - (sin(y))^2 we can now substitute it into our first identity to obtaincos(2y)...
