Mathematically, the derivative of exponential function is written as d(a x)/dx (a x) a x ln a. ( u), then f(x) 1 u 1 lnb du dx f ( x) 1 u 1 ln. The derivative of exponential function f(x) a x, a > 0 is the product of exponential function a x and natural log of a, that is, f(x) a x ln a. In your case : ( f ∘ g ) ( x ) = ln (x+1 ), f ( x ) = ln ( x ) and g ( x ) =x+1. The derivative of logarithmic functions is obtained by the following formula: if f(x) logb(u) f ( x) log b. We can use the chain rule here, naming u = 2 x and remembering that the chain rule states thatĭ y/ d x = 1/ u ⋅ 2 =( 1/ 2 x) ⋅ 2 = 1/ x Derivative of ln(x+1) Since f ‘ ( x ) = 1/ x and g ‘ ( x ) = 2, we have : In your case : ( f ∘ g ) ( x ) = ln ( 2 x ), f ( x ) = ln ( x ) and g ( x ) = 2 x. We have proven the following theorem The derivative of ln(2x) Instead, here, you MUST use the chain rule. Also, since there is no rule about breaking up a logarithm over addition (you can’t just break this into two parts), we can’t expand the expression like we did above. Now implicitly take the derivative of both sides with respect to x remembering to multiply by dy/dx on the left-hand side since it is given in terms of y, not x.įrom the inverse definition, we can substitute x in for e^y to get \(y \ln(3x2 + 5)\) Since this is not simply \(\ln(x)\), we cannot apply the basic rule for the derivative of the natural log.
