The best way to approach this question is to solve it using integration by parts.First, recognise that ln(x) = 1 x ln(x), and set du/dx = 1 and v = ln(x). We then find that u = x, and dv/dx = 1/x.With thi...

The student can choose any relevant studies to answer this question, but I would recommend the students to use either Asch, Milgram or Zimbardo. The student should use the following structure to answer th...

This method is known as the tennis match, and also serves as good revision method. It includes prior drafting of an essay, of which there is definitely time within A level exams for. Take a piece of paper...

This is a separable differential equation, so the first step is to separate the two variables. Factorise out the x from the top bracket so that the equation becomes: dy/dx = x(y^2+1)/yThe next step is to ...
