The first tip is to slow down! Way too often, you are so eager to get the oral presentation over with that you start to blurt out absolutely everything you’ve learnt in 30 seconds and then all your words get...

Roots = where line touches x-axis. Set equation equal to 0 as y=0 at the x-axis. Now we need to solve for the x values at which y=0. Quadratic is now 0=x^2+5x+6. Factorise quadratic: 0=(x+3)(x+2). Now you ca...

For your AQA English exam, you are assessed on four key categories. Each of these categories is called an ‘Assessment Objective’ - an AO. The first of these AOs, AO1, is to ‘read, understand and respond to t...

To solve simulatenous equations there are two main methods, substitution and elimintion. The first method requires the principle where if x is equal to a number, say x=2 then we can substitute this in, for e...

f'(x)= 3x^2+1/3x^(-2/3) To differentiate you need to multiply the coefficant of the x dependent terms by the powers and then the power of x goes down by one. For example: differentiate f(x) = x^n. f'(x) = nx...
