side, we find that the differential equation (2) is satisfied 6tet2 =6tet2, which holds for all t. Thus x=3et2 is a solution of the differential equation (2). Before beginning our general development of first-order equations in Section 1.4, we will discuss some differential equations that can be solved with direct integra-tion.

Applying the second order condition to ensure whether it is really minimum we take the second derivative of AC function. d 2 (AC)/ dQ 2 = + 1.0. Since second derivative of AC function is positive, d 2 (AC)/ dQ 2 > 0, output of 180 units of output is one that minimises average cost of production. 4. Multivariate Optimisation:

q d = − 3 p − t + 130. for the demand function (note that the demand is dropping with time!) and for the supply function, q s = 4 p + 25. At t = 0, this gives you the equilibrium values of p ∗ = 15 and q ∗ = 85 that you calculate. Now if we perturb p by setting p = K p ∗, ( K = 1.3 in your case for a 30% price increase) all you do is ...
