I am sure this is the last time i am bothering you steve for today! you are very helpful.
1) I have to find the population density i which r is 0.2 apart and distance is 1.2km so there are total 7 values from 0 to 1.2 , i am taking right and left end-point approximations and taking average of them, still not getting right answer?
2) Breathing cycle takes about 5 seconds.Maximum rate of flow is 0.5/L. The function often use to model the rate of air flow is 0.5sin(2pi*t/5). And volume of air inhaled in the lungs at time is given by 5/4*pi [1-cos(2*pi*t/5)]L. Find average volume of inhaled air in the lungs in one respiratory cycle

the density will be the (average value of the population) divided by the area
just as we had to integrate the density times area to get total population
.
Remember that the average value of f(x) in the interval [a,b] is
∫[a,b] f(x) dx
