WebThe answer is y ′ ( x) = 2 cos ( 2 x) 1 + sin ( 2 x). You are right about the rule. Everything inside ln must go in the denominator. The next step is to use the chain rule which says you multiply by the derivative of the interior argument of ln ( 1 + sin ( 2 x)) (i.e. multiply by the derivative of 1 + sin ( 2 x)) Share. Cite. WebHow do you calculate derivatives? To calculate derivatives start by identifying the different components (i.e. multipliers and divisors), derive each component separately, carefully …

WebApr 13, 2024 · Explanation: We could use the Chain Rule right away, but the properties of logarithms allow us to avoid that and make this easier. ln( 1 x) = ln(1) − lnx = −lnx. So, d … WebNov 25, 2024 · To prove the derivative of ln (x+1) by using first principle, we start by replacing f (x) by ln x. f (x)=lim {ln2 (x+1+h)-ln (x+1)/h} By logarithmic properties, f (x)=lim {ln (x+1+h/x+1)/h} Simplifying, f (x)=lim {ln (1+h/x+1)/h} Suppose t=h / x+1 and h=t (x+1). When h approaches zero, t will also approach zero. f (x)=lim {ln (1+t)/ (x+1)t} And, WebOct 29, 2007 · Find the derivative of 1 / ln x Homework Equations N/A The Attempt at a Solution y = 1/lnx First Attempt: y' = -1/x/ (lnx)^2 y' = -1 / x (lnx)^2 Second Attempt: ln y = ln (1 / lnx) ln y = ln 1 - ln x ln y = -lnx dy/dx = y (-1/x) dy/dx = -1/xlnx Third Attempt: ln y = -lnx y = -x y' = -1 Which one is it? =/ Answers and Replies Oct 28, 2007 #2 inward strategic consulting
