Hi, I have a problem related to the cancellation of the square root with a square in its argument, see the image below.

Thanks in advance,



Hi, I am using fsolve to find the roots x of a nonpolynomial expression f(x,a) = 0, using a loop for do to vary the values of the parameter a in small identical steps. At some stage, fsolve cannot find a solution. According to the Maple help, in this case fsolve returns a NULL sequence. I would like to know how to use the fact that fsolve cannot find a solution to break the loop with an if-then statement. 

Hi, I am trying to plot a parabola in spherical coordinates using the command spacecurve, using 



>spacecurve([cot(phi)/sin(phi), 1.61, phi], phi = -3.14 .. 3.14, numpoints = 3000, axes = normal, coords = spherical, color = red, linestyle = dash, axes = normal)


(I know it is easier in Cartesian coords, but I am doing this as a first version of a more complicated curve, given by the sol. of a system of differential equations). 

Maple plots the parabola correctly but it joins the initial and the final points of the plot with a straight line, yielding something that looks like a U with a bar on top (I cannot upload the image). Is there any way to get rid of the line?


hi, i would like to know if the classic interfase of maple 12 or higher would work

reasonably well with the 1.4GHz Intel Core 2 Solo SU3500 processor, 2GB of RAM.

if not, what would be the minimum requierments in terms of processor.
