The easiest way to solve this problem is by using differentiation . dy/dx = (6x^2 + 4x + 2)/dx dy/dx = 6 2 x^1 + 4 1 x^0 + 0 dy/dx = 12x + 4 When you set the derivative equal to zero you find a point on the ...

A bar-chart is a graph where the height of the bar measures the frequency of a particular category which that bar represents. For a histogram, however, the height is the frequency density. This means that th...

The letters "x" and "y", or any other similar letter in an equation, are examples of unknown variables . What this means is that we don't know their value, and often the aim of the game i...

We can use Pythagoras' Theorem applied to co-ordinates of these points.

A derivative is a mathematical description of how one quantity will change with respect to another. For example the 1st derivative of some function will give you the gradient of the tangent at every point on...
