Why is it that...

In pre-calculus you concentrate on about 10 different types of graphs (y=x, y=2^x, y=x^4, y=sin(x)) etc, but in calculus you are given all sorts of random graphs from all over the place and you're supposed to differentiate or integrate them without even knowing what they are?

i guess because with differentiation and integration you don't really need to worry about what the graph looks like, but when they show you how to analyze certain types of functions in precalc, find asymptotes and zeros, etc. they have to give you functions that are relatively simple.

Just a guess.

A logarithm is just a misspelled algorithm.

--No, under such circumstances it is only possible to make numerical approximations. By computer, of course.
