Example. (example 3) Since lim In(z) = In(1) = 0, we can say that the funetion f(z) = In(z) is continuous at z = 1. Problem. (problem 3) Since lim tan (z) = tan¯(v3) = x/3, we can say that the function f(z) = is continuous at z = If a function is continuous at each point in an interval, I, then we say that f(z) is continuous on I. A function f(z) is called continuous from the left at z = a if lim f(z) = f(a), and it is called continuous from the right at z = a if lim f(z) = f(a). Note that if f(z) is continuous at z = a then it is both continuous from the left and continuous from the right at z = a. If for some reason, a limit cannot be computed by plugging in, then we say that the function is discontinuous. In other words, if lim f(z) + f(a),
