To find the y value at A, we know that x is equal to zero. This can be put into the equation of the line so that 3(0)+2y=6. Therefore 2y=6, and to get the y value, we divide each side by 2, giving us y=3 ...

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...

Formulae to be used: n^th term of an arithmetic sequence u_n= u₁ + (n-1)d and sum of the first n terms of an arithmetic series S_n = (n/2) * (2u₁ + (n-1...
