Derivative of natural log rules
WebThe derivative of the natural logarithm of a function is equal to the derivative of the function divided by that function. If f (x)=ln\:a f (x)= lna (where a a is a function of x x ), then \displaystyle f' (x)=\frac {a'} {a} f ′(x)= aa′ y^ {\prime}\frac {1} {y}=\ln\left (x\right)+x\frac {1} {x}\frac {d} {dx}\left (x\right) y′ y1 = ln(x)+xx1 dxd (x) WebAnd when we take the derivative now with respect to X, F prime of X, well this is going to be the derivative of the natural log of X plus five with respect to X plus five, so that's going to be one over X plus five times the …
