I know at first a lot of the formulae or techniques you use in maths may at first seem pointless, especially if you’re not planning on going into a scientific or mathematical field, but a lot of the thing...

• rearrange equation (a) to be: y = 6 + 2x. Substitute this into equation (b) to get: (6 + 2x) + 2x = 0

• rearrange this to get: 6 + 4x = 0. Simplify to get x = -(6/4). Get the val...

I would go through one of the problem on the interactive board with the student and ask them to try next question alone.

The minimum value lies where the tangent to the curve has a gradient of zero and the curve approaching from both directions increases in value. This is done by finding the first and second derivatives of ...

1a) To simplify this into one expression you first multiply together the co-efficients, therefore 2a x a = 2a. Then for indices when they are multiplied together you add them, so the simplification would ...
