The first step in solving the equation is to find the stationary points of the function, these are the points where the gradient is equal to zero. In order to find these points, first differentiate using ...

Firstly, expanding your vocabulary will allow you to be more flexible when writing, however you need to go about learning the vocabulary in an applied way. Make sure you are able to use it in context (thi...

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.
