Hey guys, the best I've come up with so far employees the use of sinx + cos2x... this gives you 1,1,-2,1,1,-2 at 4pie/6 intervals... then uses this (-1) ^ of sinx +cos2x ... i just have to shift the graph. My teacher said he did it two other ways though... any other ideas would be appreciated...

Not really, but we never got to far into series in calc two, so i am guessing it had to be pretty simple, just no recursive series or anything like that. The teacher keeps saying its not very complicated... thanks for the help y'all

My Calculus teacher posed this question to a recent class, and asked us (previous students) if we could figure it out(just for fun). I am stumped. The question is to find the general formula that represents the infinite series (1, -1, -1, 1,-1, -1, 1...) I am assuming it uses trig graphs...

Direction field Do anybody have a hint for drawing direction field of a non-autonomous differential equation? I mean do I have to calculate as many slopes of points as possible, then draw it? Also, Can I conclude that if we use Euler's Method to estimate a CONCAVE UP/ CONCAVE DOWN...
