I never have much luck when something says "prove something <= something else". I usually just fiddle around and occasionally get lucky and reduce it to a constant < an express I know can't be less than that constant. But most times I can't reduce it to something like that. Is there any kind of "principled" approach that someone can suggest/ point me to read about?(adsbygoogle = window.adsbygoogle || []).push({});

As an example, say it was something like

[tex]ln(1+a) \leq a^2 b[/tex]

How would you approach something like this?

Thanks,

Dave
