MarcLeclair Group Title

Use L'hospital rule to find the following limit: Lim x-->0+ 6(tan(4x))^x I did this: Lim x-->0+ xln 6(tan(4x)) which is the same as: ln 6(tan(4x)) / (1/x) Take the derivative: (1/6tan(4x))) * 6(sec^2(4x))(4) / (-1/x^2). But I can't find a way to cancel out my denominator :/ the answer isn't infinity either

    \[x\ln(\tan(4x)\] \[\frac{\ln(\tan(4x))}{\frac{1}{x}}\]etc

    \[-4x^2\csc(4x)\sec(4x)\] i think is the next step

    \[\large= \frac{ 4x }{ \sin 4x }\frac{ -x }{ \cos 4x }\] there is no problem

    your sin will make the denominator 0 even if multiplied :/
