This problem is a graphical representation of finding the solutions to a pair of simultaneous equations. In this example we will use the curves y=2x 2 , and y=x 2 +1. This is a very straightforward example, ...

First things first it will definately be useful to make a quick sketch of the x-y axes, the two points, and roughtly what the perpendicular bisector will look like. This kind of question can be made much mor...

Maths has always been a passion of mine from a young age. I've always enjoyed helping others with their maths as I find it extremely stimulating.

How you should approach a question of this type in an exam Say you are given two lines: L 1 and L 2 with equations and you are asked to deduce whether or not they intersect. For example: L 1: r 1 = (a 1 ,b 1...

We label each equation 3x + 4y = 5 (1) 2x – 3y = 9 (2) We now want to get rid of one of the variables (x or y). Lets get rid of x: We need (1) and (2) to have the same number of x's so we multiple (1) by 2 a...
