Can anyone upload notes or textbooks for A-Level Further Maths? (PDF preferred)
Where I live textbooks for this particular subject are expensive af, and my school doesn't offer notes.
I have no material to go on with learning those though lol
prove basis case
assume k-th case
Find (k+1)-th case from k-th case
Since let k-th case = basis case
Row multiplies columns
approximate functions as (infinite) polynomials centred about a point x0. A special case is when x0 = 0. This can also be called a Maclaurin Series (dude was MLG, professor of Mathematics at Edinburgh at 19.)
Vectors in 3d space:
u = ai + bj + ck
v = di +ej + fk
u.v = ad + be +cf
v is perpendicular to u if the dotproduct is zero.
uxv = (bc - cb)i + (ca - ac)j + (ab - ba)k
Complex numbers & polar coordinates:
sqrt(-1) = i
a complex number is any number a + ib where a,b are real.
can be written in the form r(cos(x) + isin(x))
= rexp(ix) where r is the radius and x is the argument.
literally trig functions with complex arguments.
The rest is bollocks.
By the time you hit uni this shit will be effortless.
Some of this stuff I've learnt on my own - in Pure Mathematics 3 of normal Maths. Thanks tho.
Found Edexcel FP1 and FP2 textbooks using torrent sites btw, but not many seeders.
