No, we're still going through the last bits of calculus, but we did a mock today and I got an A^ so hopefully it will be ok as long as no circle questions come up!

Further Maths isn't timetabled at my school so it is mostly self taught - I'm just doing a past paper a week and seeking help with the questions I don't understand.

that's good I haven't tried a past paper yet!! my class learnt circles last week but i missed the lesson as I was at the dentist, hopefully i can pick it up my teacher did recommend 'mr bartons' website for further maths help, i haven't been on it yet but i have heard good things about him. good luck in yours
I have been using that website, it does seem to be the best out there.

Thats good! I need to try past papers but I want to try and learn everything first so I'm more confident. I missed the lesson on circles so I hope I pick it up from copying out notes. Mr bartons website is supposed to be good. Good luck

Hi, I'm also taking further maths this year. I really enjoy it and I hope to get a good grade because I want to study A level maths and further maths next year. My teacher is amazing at teaching further maths so we have learnt pretty much everything and am now just revising for the exam

I need help with a question. A serious A***+ question.

A function,  f , is such that  f(x) = x^4-2x^2+1 .
(i) Solve the equation  f(x)=0 giving all solutions in their exact form.

(ii) Find the coordinates of the stationary points of the curve  y=f(x) .

(iii) A line segment is drawn between two of the stationary points of the curve  y=f(x) forming a diameter of a circle. The line segment drawn is drawn such that the circle has the greatest circumference.
Find the equation of the circle in the form  (x-a)^2 + (y-b)^2 = r^2 .

i just factorise the first one as if it were a normal quadratic and work out the solutions
ii Differentiate f(x) and equal to 0. Find the value(s) of x

iii work out the coordinate of the midpoint of the diameter to work out the radius. You may need to use Pythagoras. Square the radius to get r squared. a is x of centre b is y of centre

I really like further maths, predicted an A* but I've never got anything less than an A^ in mocks and practice papers.
Only planning on working on the stuff I find hard (so that'll be angle between a line and a plane/angle between 2 planes, circle theorems, ratio (yeah this really is a weakness for me), and proof)
Both of my further maths exams clash with others!! Really frustrating!

I'm sure planes are not in further maths spec GCSE?

Are you on about the level 2 certificate? Cause I am and they're most definitely on there

Factorise x^-4 - 25y^4.
Any help would be appreciated.

Difference of two squares.
 (x^{-2}-5y^2)(x^{-2}+5y^2) .

Why is the power of two negative? I just solved it as (x^2+5y^2)(x^2-5y^2)

AQA level 2 further maths GCSE? I just double checked the specification. Coordinate geometry is in 2 dimensions only. Is this a new specification or have you been lied to?

You said factorise  \displaystyle x^{-4}-25y^2 . Expand yours out and see what it comes out as. You posted in the question a power of x^-2.
Unless that was a mistake in your question?

Neither...its come up in multiple past papers that I've done. It's basically Pythagoras and trig in 3 dimensions, so it might be under that in the spec?
