WebNov 10, 2024 · Likewise we can compute the derivative of the logarithm function log a x. Since x = e ln x we can take the logarithm base a of both sides to get log a ( x) = log a ( e ln x) = ln x log a e. Then (3.6.6) d d x log a x = 1 x log a e. This is a perfectly good answer, but we can improve it slightly. Since sims 3 cat whiskers
