centre (10,5) ? radius root 20

therefore ?

yes well done.

The frog one looks very familiar - I think it's from a Ruse paper or something but I can't remember...

Check again. Oops sorry you are correct, I mis-read.

get off this site!!!!

Thank you.

this.

That should be right if the denominator was right.

let k = the constant of dx/dt

dy/dt = (12xk)/ (1+(3x^2+5)^2)

if x-> infinity, dy/dt -> 0

x-3ln(x+1)

Fuck off SpiralFlex.

yep

(i)

If k is a positive constant, show that the area bounded by the curve y = f(x) and the lines x = 0 and x = k and y = 1 is always less that LN 2.

(ii) - find the horizontal asymptote of this function.

 

[barbernator]

ii)horizontal asymptote: y=xsin(1/x)??

 

[Drongoski]

So the asymptote is y = 1.

Prove by induction that:



is divisible by 100 for all integers

lol i wish that was in this year's exam instead of last year's.

 

[barbernator]

CBF, mathematical induction is easy anyways

P(x) is an odd polynomial of degree 3. It has (x+4) as a factor and,
when it is divided by (x−3) , the remainder is 21. Find P(x).
