# bloody triggernomitry
or how you spell it dave


EDIT: the calculator i used for Alevel math for these i stole off a 12 year old, how brilliant, £8 saved

# if i coulf be botherd id work out
the line equation o those graphs...

but i cant be arsed

# hmmm
and that would take A LOT of working out

# No...
a - Cos X
b - Sin X
(Guineapiggy Fuzzeh!, Wed 9 Nov 2005, 23:22, archived)
# or
sin x and sin (x+ pi/2)

# Pfeh, my formula is nicer
I rule this game damnit!

# not really
just need 3 points on a graph

2 intercections of X

and 1 intersection of Y

and you get somthing like Y=X3 =(a x pi)X2+(b x pi)X+c

# Trust me, you can't do it that way.
This isn't a polynomial

# that may be true actually
tis just a sign-wave graph

polynomial: -

# Nicely doodled
Paint?

# yup
let stop this thread...

much to late for maths talk

# err...
cos(x) = 1 - x^2/2! + x^4/4! - ... (a polynomial)

sin(x) = x - x^3/3! + x^5/5! - ... (a polynomial)

aicmfp again!

# In a polynomial the powers have to be positive integers

# i think i should be charging for these lessons...
a) powers don't have to be positive for it to be classed as a polynomial (I think)
b) they aren't even negative in the above.

The first is the differential of the second.

As proved by a complex Euclidian representation of either.
