Well how much do you understand about it? Have you got any ideas at the moment?
(Then I would work through the multi-staged question with them)
1) What equation do you use to work out these type...

This is an example question where you integrate by parts twice. When answering a question like this it is helpful to memorise general integration formula, so you can quickly and confidently tackle questio...

To find the determinant of this matrix, we calculate: 2(1x5-3x7)-1(2x5-6x7)-1(2x3-1x6) = 10 - 42 - 10 + 42 -6 + 6 = 0.So the determinant of this 3x3 matrix is equal to zero.

Step 1: The denominator of the right-hand fraction is quadratic, so we can factorise this to (x+3)(x-2). This looks similar to the denominator of the left-hand fraction, suggesti...

First of all expand the brackets in the equation. Then you can differentiate each term with respect to x. As one of the terms will be a product of x and y the product rule must be used to find the differe...
