Question

is there any other way to solve logarithmic differentition ? I mean it seems we can solve it by derivative rules am I correct ? thnx in advance

Answer 1

no I mean like x^5 / (1-10x)*(\[\sqrt{x^2+2}\] )

Answer 2

my question is, do ı have to apply the logarthm derivative rule here ? I can solve in other way it but it will take long thats why ı am asking.

Answer 3

Sorry, I spaced out about logarithmic differentiation. I know what you mean. You take the logarithm of the function, then derive what you get, and then multiply back by the function. So what is the question about it, when to use it? The example you have given I would probably not use it there, that seems like it'd be easier to just use the regular rules.

Answer 4

They may have given you as practice some examples that you can solve by logarithmic differentiation but that you do not necessarily need to solve by logarithmic differentiation, just as practice. That is not a bad idea, because then you will have practiced it when you run into cases where you actually need the method.

Answer 5

OK then, ı was just confused tahnk you very much
