Problem

A population P(t)P(t) (measured in hundreds of organisms) satisfies dPdt=0.03P(1−P50)\dfrac{dP}{dt}=0.03P\left(1-\dfrac{P}{50}\right) with P(0)=10P(0)=10. A numerical algorithm will approximate P(10)P(10) using a uniform step size hh over the time interval 0≤t≤100\le t\le10. Experience with this algorithm on similar problems shows that the global error at t=10t=10 does not exceed 4h4h. You must design a computation whose approximation of P(10)P(10) is guaranteed to be within 0.020.02 of the exact value. a. Determine the largest step size hh that meets the stated error requirement. Then state the corresponding minimum number of time steps that must be carried out over 0≤t≤100\le t\le10. Show all work clearly.
