Probably a simple Maple syntax error(hopefully). Help? :) 1. I'm working on a research project. I've used this exact syntax below before and it worked on maple. I tried it a couple weeks later on the same computer in the math lab, and it didn't work. Then I tried it on my laptop- I think it is just a syntax- maybe someone can help me without knowing the theory behind the work. Anyways, here's what I type into maple (tell me if you need the maple output) c:=0.0012; s:=-1.5; m:=-2.8 f3:=1+s+c*[1+(1/(x^2))-(1/((1-x)^2))]-2*m*x; (At this point everything is fine; the function is defined and the only unknown in the function is x) Then, it's time for me to graph so f3 vs x, so this is what I type: plot(f3,x=0..0.69); I thought maybe the problem was the division by 0 (even though it should just give me an asymptote), I changed it to plot(f3,x=0.1..0.69); No luck even with this. The error I get is "Warning, unable to evaluate the function to numeric values in the region;see the plotting command's help page to ensure the calling sequence is correct." I'm frustrated because I got this to graph before with x=0..0.69. I know this graph is located in the first quadrant. I really hope it's a simple error. Any hints or suggestions or anything would be appreciated. I went to the maple site to troubleshoot, and it doesn't seem to me like I have the errors they listed.
