Is the derivative of sin(3x) just 3sin(3x) because of the chain rule? IE, let u=3x, then 3sin(u) => 3sin(3x)(adsbygoogle = window.adsbygoogle || []).push({});

Thanks.

Ok, I am pretty sure that is true. How about, [tex]

\lim_{t\rightarrow 0} tln(t)

[/tex]

What is the common approach for this problem?
