1. The problem statement, all variables and given/known data Compare the triangular wave form in fig 6.5 with the graph of V(t)=1+(8/(n*pi))cos(2000*PI*t). Sum V(t) for odd integers of n from 1-19(1,3,5,7,9,..) and graph using a computer for 0<t<2. compare with the graph shown in the text. 2. Relevant equations shown in problem. For the sum I just added the equation in my ti89 a bunch of times since i could not get matlab to work. here is the equation i got. V(t)=(248303008*cos(200*pi*t))/(1459535*pi^2)+10 I'm not at all sure this is right and kinda don't think it is but i can figure out how to get matlab to sum it up for me 3. The attempt at a solution x=0:0.001:2; y=1+(8/(pi^2))cos(2000*pi*x.); plot(x,y); I this doesn't work right, and the one way i sort of got it to work it was just a straight line, which makes me think the equations is messed up. I'm quite frustrated with matlab right now as I have been having issues with it all week and really want to punch this 30inch screen at my schools computer lab. thanks for any help.
