I just demolished that pizza

banana going across and the skin making the vertical bars

[Smiley73]

sort of...

Just had a most embarrassing moment.... screeching at moi brother to run after teh ball "FASTER YOU SILLY BOY, YOO IS MOVING LIKE AN OLD MAN!!!"

And in teh exact moment I uttered teh last two words, moi eyes travelled to le track beside the footy pitch where un rather elderly gentleman was walking along and looked vair vair surprised.....

[Crimson_Ayla]

What kinda pizza?

[Smiley73]

What kinda pizza?

 

smokey joe I think

 

mince, sweet peppers, onions

[Smiley73]

SMOKEY JOE • chicken OR ground beef with onion, mixed peppers & smokey BBQ sauce

[Crimson_Ayla]

Sounds nom

[Crimson_Ayla]

And reminds me how lacking in food I am

[Smiley73]

Ayla, yoo there?

[Crimson_Ayla]

Yarr

[Smiley73]

oh god, sometimes I mare at normal maths

[Smiley73]

I can derive the formula to prove my point but I can't use it properly >.>

 

that formula being quadratic patterns <.<

[Smiley73]

Yarr

 

can you figure this out?

 

 

f(x) = 1 - x^2 and g(x) = sin(pi - 3x)

 

I underlined the confusing part

[Crimson_Ayla]

Just how to get from cos(3x) to 1- (9/2)x^2?

[Smiley73]

yeah

[Crimson_Ayla]

Ok, well I dunno if you've heard of a Maclaurin Series or Taylor Series? You can write more complicated functions as infinite polynomials. The series expansion for cos x is 1 - (x^2)/2! + (x^4)/4! - (x^6)/6! + ... When you sub 3x in, you get 1 - (9x^2)/2! + (lots of other terms that are insignificant as x tends to zero)

heard of it is passing, that's fine then thanks. I thinks this is an old worksheet
