<p>Hey Folks,</p>
<p>I've got a pretty simple question here. I use maple to check my work and I'm wondering how  to get a numerical approximate of a Riemann sum containing a trig function. I don't want sin in the answer. For example:</p>
<p><maple>(1/40)*Pi*(Sum((1/40)*sin*i*Pi, i = 1 .. 10))</maple></p>
<p>A<maple>pproximates to 0.33928 sin.</maple></p>
<p><maple></maple><maple>Any help would be greatly appreciated. Cheers.</maple></p>

evalf in the end...

Sometimes I realize that I need a approximate result rather than an exact answer after I enter Maple command. Is there a way to apply the evalf command at the very end of an input? Thanks in advance!!

I am using Maple 12 on Windows XP.  When I export a plot to postscript as follows

plotsetup(ps,`filename.eps`,plotoptions=`width=2in,height=3in`);
plot(...);

the width and height options seem to have no effect.   The graphic is always 19.579 cm by 19.579 cm.  Other options such as portrait and noborders do have an effect.  Any suggestions for why this is not working?

Hello I have a problem with running Maple 12. Every time i try to run it i get the java virtual machine error. This must happen to alot of other people too because i did some looking around to find a solution. I found some solutions, like delete the # in front of maxheap=700m or lower the maxheap to maxheap=650m in launch.ini in the bin.win in the Maple file.

I used Maple 12 to calculate the volume of a shpere of radius r by using Integration technique. when I entered the first expression, Maple 12 returns the expression as it is. When I enter a different expression for the same problem I get an exact answer. This has happened before...I am not sure what's going on....

Solving Coefficients...

Hey there,

 

let say I have an equation like that:

2.5665*x+3.79094*x^2+3.52723*x^3+2.1137*x^4+.76839*x^5+0.0911*x^6-0.076*x^7 = x*(a[0]*x+a[1]*x+a[2]*x^2+a[3]*x^3)^(13/9)/(c[0]+c[1]*x+c[2]*x^2+c[3]*x^3+c[4]*x^4)

 

what Maple iteration utility that I can use to solve for a[0], a[1], a[2], a[3], c[0], c[1],c[2],c[3] and c[4] when x--> 1.14?

 

Thanks



 

This is my very first time using Maple or any program like it, so bare with me. I need to generate 50 random 4x4 matrices with entries in R and 50 more in Z. I also need to find out how many of them have the determinate of 0. Could anyone assist me in how I would go about doing this? Any and all help is appreciated. Thank you very much. Thank you, James D.
