one question summed up:

x(x-1)y''+3xy'+y=0

show x=0 is regular singular point

turn into a power series

find r from indicial equation

find the recurance relation

produce a series solution for highest value of r

how solution can be simplified to y=(Cx)/[(1-x)(squared)]

feeling like a genius :cool:

The Mix Honorary GuruThe Mix Honorary Guruthankfully its long been replaced by much more important things in my head

who thinks up these questions anyway? the only maths i ever need now is adding, subtracting, multiplying, dividing and the odd percentage, i could have stopped maths in P7 if that was all i would ever use

The Mix Honorary GuruIntegration is about where my ability stopped.

The Mix Honorary Gurunot useful in real life, solving equations of tat type, gives you enrgy levels of Hydrogen which has all sorts of scientific uses

and maths is like languages the basic logic and methods have to be drummed in at a young age

The Mix Honorary GuruThe Mix Honorary Guruchrist almighty you actually know what that means?? :eek:

The Mix Honorary Guruy' is the 1st derivative

y'' is the 2nd derivative

using this info and that equation above we supoosed to generate what y is in terms of x

The Mix Honorary GuruThe Mix Honorary Gurucompletely useless to my life now though. i own a calculator.

The Mix Honorary Guruoh well. I can barely count to 10 so there's no hope for me with all that complicated stuff

The Mix Honorary GuruIt understand what it means too.

I'd just be frigged if I knew what to do with it.

The Mix Honorary GuruThe Mix Honorary GuruIs that first year maths?

It just seems a little bit harder than what I did at a'level, that's all.

The Mix Honorary Gurui do chemistry with maths

so it not as hard as maths students but next hardest thing
