My equation was P= 61-6e^-4t +8t^2 but a lot of people got different to me 💀. Most people got around 60 children though? (mine was 62.2)

Nice same. Why did alpha have to be negative?

And what was the reason for the particular integral not being correct.

I said something about decay and there was already a constant in the complementary function

What did everyone get for their value of p?

opposite for me, the first one was near perfect, this one was ok

i said alpha was negative cos if it was positive and C>P then dC/dt = a(C-P) increases indefinately which goes against that children move from the busy to empty room

i put it in my calc and got one arctan but that didn't show working so I just said some stuff about triangles

Really. I was integrating 1/u^2 +16. U was my substitution with limits one and 3

yea you do that and end up with pi/4(two tan^-1 s) and to combine those i just put it in my calc and got a rational number but that's probably not allowed so i said stuff about triangles to make it look like i got that properly

Ohh smart. It’s 8/19 then isn’t it
