1. f(x) = ln(2x) 2. f(x) = ln(√x) 3. f(x) = ln(x² – x – 2) 4. f(x) = ln(cos x) 5. f(x) = x²ln(x) 6. f(x) = log2(x² + 1) 7. Logarithmic Differentiation: The derivative of a function y = f(x) may be found using logarithmic differentiation – 1. Take the natural log of both sides of the equation. 2. Simplify using the log rules. 3.

Taking ln of both sides gives y = ln(x + ). In calculus one of the main applications of hyperbolic functions is to do certain integrals. In order to see how they are used, we first have to look at the derivative formulas for the inverse hyperbolic functions.

The natural exponential has a slope (derivative) of 1 at 0 and exp(0)=1. Therefore, the first order Taylor approximation is. ... A difference in x by a factor f is associated with a difference in y in the amount b1 ln( f ). Proof: ynew = b0 + b1 ln( f x) = ( b0 + b1 ln(x) ) + b1 ln( f ) = yold + b1 ln( f ) ...

ln Y = ln A + a * ln L + (1-a) * ln K Observing that Y, A, L, and K change (grow?) over time, we can take the derivative of this log-linear form. Recall that d(ln X) = dX / X which can be interpreted as the percentage change in X.
