So, my instinct in answering this question is a definite NO. There are a lot of terrible myths going around that present Oxbridge interviews as some kind of MI6 screening scenario . I remember when I was ...

Yes of course.
I will start with an example. Try and solve these simultaneous equations I will talk you through the model answer below.
3x + y = -4 3x - 4y = 6
Notice both equations contai...

First, we will write out the equation, writing the root x values in a way that allows us to differentiate them. Root x can be written as x^1/2 and 4/rootx can be written as 4x^-1/2. Now we can differentia...

Although the name sounds scary, it is easier that it seems. In Latin when a gerund has an object, there is a tendency to harmonise the terminations of the two, so the object will agree with the sense of t...

Point P has x-coordinate 4, to work out the y-coordinate you should substitute x=4 into the equation of the circle. This gives you 16 + y^2 = 80. this can be rearranged to y^2 = 80 - 16 = 64. Therefore y...
