4; yiz=x* — x^; y^ = x* — x\ Ex. 24. Construct and discuss the equation x = log y. Results.—Assuming x as given in the following table ofvalues (any convenient values of x maybe taken), thevalues of y can be found from a table of logarithms. For x= 0, y = 1. X = .2, y = 1.58 nearly. a;= .4, 2/=… … Fig. 16. Locating these values, we have the curve MN, Fig. 16, which is called the Zogarithmic Curve. It lies wholly above the axis of abscissas, as negative numbers have no logarithms. It extends on both sides of the axis of ordinates, and cuts it at (0, 1,) a point through which all logarithmic…
