'lemda' is the adjustment coefficient of excess demand which is considered as positive excess demand; law of demand, in general, states opposite relationship between demand and price, so 'bita' is positive because of the negative sign before it.
@@rcdsir1297 the rate at which the volume of sales(q) for a good increase after an advertising is given by dq/dt=0.02(300-q).it is given that q=0at t=0,where q is the number of good sold and t is time in year. solve the differential equation .sketch the solution curve and hence describea how the volume of sales should increase in time
Sir why should the term with the 't' i.e lemda,bita needs to be positive?
