1. Solve the differential equations: a) Write solution as function of x: (sec x) dx = ey+sin x dx b) In some chemical reactions, the rate at which the amount of a substance changes with time is proportional to the amount present. For the changes in 8-glucono lactone into gluconic acid, for example, dy = -0.6y when t is measured in hours. If there are 100 grams of 8-glucono lactone present when t = 0, how many grams will be left after the first hour? dt
