Taylor Series???

[slanders09]

Quick question, i know that on the last page of number crunchers on the calculator test there are little shortcuts to work them faster...trig identies, the [unparseable or potentially dangerous latex formula], [unparseable or potentially dangerous latex formula] and the squared expressions, but i havent been able to figure out the questions like...
[unparseable or potentially dangerous latex formula]
...are there any others i should know?

Watch your radius of convergence!

more to memorize...yay!!! but thank you very much. i tried to find what they were, but never could.

This stuff is funny. The only punches I can think of that I ever reduce are the [unparseable or potentially dangerous latex formula] types and the [unparseable or potentially dangerous latex formula]. I've always been afraid of trying to find clever shortcuts in case the approximation is insufficient or something...probably explains why I'm, as far as I know, the slowest puncher on the Lubbock Calc team. =)

Radius of Convergence...ay, there's the rub with using these little shortcuts. Often times its worth 3 or 4 extra seconds of crunching to make sure you get these correct. But thats just my opinion.

I think one cruncher was a partial sum of a McLaurin series, but the answer came out to be at least two hundreths off. In the long run, I don't think the series tricks bring down your time enough to be that concerned.
