Differentiating ln f x
WebNov 22, 2016 · I was taught to remember the rule in words; " The first times the derivative of the second plus the derivative of the first times the second ". This can be extended to three products: d dx (uvw) = uvdw dx +u dv dx w + du dx vw. So with f (x) = x2lnx we have; {Let u = x2 =⇒ du dx = 2x' And v = lnx =⇒ dv dx = 1 x'. d dx (uv) = u dv dx + du dx v. WebLet us prove that the differentiation of ln x gives d/dx(ln x) = 1/x using implicit differentiation. Proof. Assume that y = ln x. Converting this into the exponential form, …
