To integrate this, we use the product rule. Think of it as intergrate [ 1 x ln (x)]. As by the product rule we chose one to intergrate and one to differentiate. We intergrate 1 to get x. We differentiate ...

Multiplying indices is much easier then it first seems. First you need to undertand what an index or power is, A^2 (A to the power of 2) means AxA, A^3 (A to the power of 3) means AxAxA and so on. The dif...

The degree of a polynomial is the highest degree of the polynomials in your equation. For example, if you had (x^4 + 3x^2 + 5x), then the degree of the polynomial would be 4, as the largest polynomial in ...

the method to complete the square is as follows; -take the constant (13) away from both sides of the equation leaving x and x^2 terms only on one side of the equation: x^2+8x=-13

-Add half of the v...

I always find with simultaneous equations that it is first important to remember what you are actually trying to do- to work out the values of x and y given what you know about them. So lets use this exam...
