d dx lnx = 1 x But we cannot use lnx in this example because, here, x runs from −2 to −1, and in particular is negative, and lnx is not defined when x is negative. A variant of lnx which is defined when x is negative is ln(−x) = ln|x|, so let’s compute d dx ln(−x) = 1 −x (−1) = 1 x by the chain rule.

d dx ex = ex ⇒ Z ex dx = ex +C. • dm dxm e x= ex > 0 ⇒ E(x) = e is concave up, increasing, and positive. Proof Since E(x) = ex is the inverse of L(x) = lnx, then with y = ex, d dx ex = E0(x) = 1 L0(y) = 1 (lny)0 = 1 1 y = y = ex. First, for m = 1, it is true. Next, assume that it is true for k, then d k+1 dxk+1 ex = d dx d dxk ex = d dx ...
