Task 1 Task 2 aº = 1, when the exponent on a increases, the power itself increases, provided a is greater than 1. It follows that if the exponent is infinitely small and positive, then the power also exceeds 1 by an infinitely small number. Let w be an infinitely small number, a 1+ where is also an infinitely small number.... we let = kw. Then we have a = 1+kw, and with a as the base for logarithms, we have w = log (1+kw). EXAMPLE In order that it may be clearer how the number k depends on a, let a = 10. From the table of common logarithms, we look for the logarithm of a number which exceeds 1 by the smallest possible amount, for instance, 1+ 1000000 so that ku = 1000000 Then log (1 + 1000000) = log100000 = 0.00000043429= w. Since kw=0.00000100000, it follows that=10000 and k = 10000=2.30258. We see that is a finite number which depends on the value of the base a. If a different base had been chosen, then the logarithm of the same number 1+kw will differ from the logarithm already given. It follows that a different value of k will result. plot ya and y = 1+kw for a = 10 and k = 1000 2.30258. Euler claimed these quantities a" and 1+kw should be identical for "infinitely small" w. Would changing the value to something else, say -3, change anything about your plot and this claim? 43429 plotting y = 2 and y = 1+kw together. estimate k for a= 2. Get a visual check by Since a = 1+, we have a = (1+1), whatever value we assign to j. It follows that + kw 3 + 1 = سالی 10 - 1) 22 - 10 - 1) (6 – 2) 33 + + 1-2 1-2-3 If now we let j =, where z denotes any finite number, since w is infinitely small, then j is infinitely large. Then we have w, where w is represented by a fraction with an infinite denominator, so that w is infinitely small, as it should be.
