So I have this as the last thing I don't understand before tommorrow's test.. I have tried reading in the book and online, but it's just not clicking for me! There are so many numbers, and it they seem to just plug them in from nowhere. Like some example problems would be like sqrt(25.1) and 2.001^5. Supposedly I use the equation L(x) = f(a) - f'(a)(x-a)? But I have no idea which numbers I plug in where.. is this easier than I'm making it to be?
