It’s also possible to have trig limits involving sec, csc, or cot. The best bet is to write it in terms of cos, sin, or tan. For example, \lim _{x \rightarrow 0} \sin (3 x) \cot (5 x) \sec (7 x)=\lim _{x \rightarrow 0}(\sin (3 x))\left(\frac{1}{\tan (...

as i noted earlier, what we mean when we say "f is differentiable", is that some sort of limit involving f exists, for certain values of x. and in order to use useful things like rolle's theorem, we need to know when it's "safe" to do so. those "fine print" caveats at the ...
