Question

How do you integrate this please??

dr/dt = 2r(1-r)

Answer 1

nice job mimi

Answer 2

\[\frac{dr}{2r(1-r)} = dt\]\[\int\limits{\frac{dr}{2r(1-r)}} = \int\limits{dt}\]

Answer 3

[1/2r(1-r)]dr=dt
=>integrating on both sides
1/2log r -1/2 log (1-r)=t

Answer 4

the first part by partial fractions
\[\int\limits{dt} = t\]

Answer 5

Thanks guys!
