First rearrange the equation to get 2y = 7x + 11.Then divide through by 2 to get the equation for y: y=7x/2 +11/2Now differentiate with respect to x to find the gradient function: dy/dx=7/2 + 0We hav...

Once you have found the stationary point of the equation by differentiating the equation and equating it to zero. You can then find out if the point you have found is a maximum, minimum or point of inflec...

To begin with we see that y=x³-9x is a positive cubic function, and therefore we know its general shape.The first step is to find the x interecepts. We do this by setting y=0 and solving the re...

Globalisation factors refer to the elements that drive globalisation and cause globalisation to occur.Before understanding the factors of globalisation we must first understand the meaning of globalisatio...

Depending on the location, coastlines can be categorised as high energy or low energy.-High energy coasts are usually characterised by:-Strong wave action, typically during the winter months-The rate of e...
