About me

I'm currently in my second year at Bristol Uni, studying Maths. I'm available for tutorials in Maths and Further Maths (both GCSE and A-Level). I am able to tutor all GCSE topics and any of the following modules at A-Level: C1, C2, C3, C4, M1, M2, S1, S2, FP1, FP2, FP3, D1.

Having gone through GCSEs and A-Levels myself recently, I know how valuable some extra help outside of school can be, whether it's to get another explanation of tricky topics at a pace that suits you, or just to get the extra bit of practice needed to answer questions independently every time.

I look forward to meeting you.

Ellie gave me an understanding of topics that I was finding difficult, and went through appropriate questions that could appear in my exams. Clear and helpful explanations.

Questions Ellie has answered

How do I find the maximum/minimum of a function?

The maximum/minimum of a function are the points where the first derivative (the gradient) of the function is zero.

So with a function of the form y=f(x), you must take the derivative (dy/dx) and set your result equal to zero. This equation must then be solved for x, to find the x value(s) for which the function is a maximum or minimum.

To determine which values are maxima and which are minima, you must take the second derivative of the function (this means differentiating the original function twice) and substitute each of the x-values found above into this equation in turn. The values which give a positive output for the second derivative are minimum points and the values which give a negative output for the seond derivative are maximum points.
