Elements of analytical geometry and the differential and integral calculus (1856)
Robinson, Horatio N. (Horatio Nelson), 1806-1867 · Cincinnati : J. Ernst · leaf 252
cannot be 1, for every power of1 is 1, and in that case the variations of x would produce novariations in y. Let MBMhe the logarithmiccurve whose equation is y=a,and make x=0, then we shallhave y:=a°=l=AB,and this will be the value of AB,whatever be the value of a, show-ing that all logarithmic… … 244 DIFFERENTIAL CALCULUS. When X is large, a small variation in x produces a much greatervariation to y. When X is negative, the equation becomes showing 2/ to be a fraction, or less than unity, but y cannot be-come zero until x becomes infinite and negative, showing thatthe curve will meet the…
