58), we find that cv = mg or v = mg/c, which is the value given in the last formula. 56), at least when the time interval is short. The latter formula was derived in the absence of a damping force (c = 0). 60) in a Maclaurin series, -aim = 1 (ct/m)3 l , ( Cf / m ) 1! 2! 60). 52 I Introduction to Differential Equations In the case of a body falling from a great height we can no longer assume that the force due to gravity is constant. Instead we must use the more accurate "inverse square law" of Newton.

Let x(t) and y{t) denote the concentrations (in molest per liter) at time t of A and B, respectively. In our first example, we shall assume that one molecule of A combines with one molecule of B to form a new product or products. Then x and y t If the molecular weight of a chemical is w, then one mole of that chemical consists of w grams.
