Differentiation is a relatively easy process once you learn the basic method. The basic rule is, you multiply the coefficient of x by the exponent, which becomes the new coefficient, and then reduce the expo...

Lots and lots of past paper questions! Any other questions as well really. When it comes to maths, practice makes perfect. Every time that you answer questions from a specific topic, you develop an extra bit...

An example of a pair of simultaneous equations is as follows: 4x + 3y = 10 (1) and 2x - 3y = 14 (2) Now to solve these equations we can simply add them and solve for x, then sub that value of x in to one of ...

Factorising equations: Lets look at the example: Factorise 3x+21 In order to factorise this equation, we need to find a common factor of both 3x and 21. For this equation, the common factor is 3 and so this ...

FIrslty to avoid confusion: x = the variable x X = multiplication. When you differentiate an equation, the derivative (answer) is referred to as dy/dx. For a polynomial as in this question you take each term...
