MaplePrimes Questions

I'm going through Francis Wright's COMPUTING WITH MAPLE. c2002, and based on Maple6. can anyone explain the reason for the output that I get just for the last statement alone dealing with the change of base for logarithms ? >
umm....is this site for maplestory??? how do i get a faster better maplestory? plz help
Compiler:-Compile uses a preset set of compiler flags. But for example I would like to replace -O2 by -fast, which is a special flag for the Mac G5. Is there any way to do this? I would even be willing to dig into the Maple code responsible, if I knew where to dig.

I am working with Maple 9 and I am trying to create some kind of density plot similar to the one shown below this message (this one was created with matlab). I haven't yet figured out how to get a density plot with a color gradient and a scale (or legend) at the site of it which shows which color corresponds to which density value. Actually I want to plot a capacitor (or inductor) current and stored energy in an inductor (two different diagramms) which are depending on the input current and the output voltage. This should happen in a similar diagramm shown below. I would be very thankful if you could help me to solve this problem.
Hi, I just started using maple yesterday. I got version 10 and was wondering how I could get a definite integral for the function below. For some reason whenever I try to, it doesn't give me an actual numerical answer but a restatement of the statement. The function is: (sqrt[x^2-0.2^2]/sqrt[x^2-0.3^2])*(0.3/x) Thanks in advance.

Hello - thanks rcoe for your previous post. One of my students encountered a system error after clicking the link to his assignment and entering his username and password. I created a "fake student" and was able to recreate the error a couple times after randomly opening and closing some assignments. The error stopped occuring after I logged in as the instructor and cleared any active assignments the student had. I am running Maple TA version 2.0.1. Is this a bug or do you have any suggestions on how to avoid this error in the future? Here are the two error messages I received (at different times):
I've looked at Alec Mihailov's interesting web page describing how to use the Microsoft assembler (MASM) to create a DLL that can be called by a Maple procedure. I'm attempting to rewrite the code using the GNU assembler (as) and have a few questions. Page 331, section 6.2 of the Maple 10 Advanced Programming Guide states that, to create a DLL, "the external library functions must be compiled by using the _stdcall calling convention, which is the default under UNIX but must be specified when using most Windows compilers." This leaves me somewhat confused. My limited understanding is that the stdcall calling convention has two effects:
I recently gave a Maple T.A. assignment to my students, and now I'd like to extend the deadline by a day or two. Should I be wary of any side-effects to changing the due date after students have started working on the assignment? Thanks, Marc (I mean technical side-effects, not the side effect of having my students think I'm a pushover :)
I have been using Maple 10 for a couple of months. Reading from the User Manual and working with the program to get up to speed. I can write functions and procedures just fine, and they work great within the worksheet that I have open at the time. I want to be able to save these items for use in other worksheets or documents later on. I have not been able to find a way to save, recall or send to a custom library. What is a boy to do? Sincerely, Daniel Cahoon
I'm trying to use evalb to see if two versions of an expression that i'm comparing is true. here is my input please bear with me i don't know how to enter symbolic math into these posts yet. evalb ((1/2 (2^((1/4)) (((a)/(Pi)))^((1/4))* (e)^((-1/4 (k^2)/(a))))/(sqrt(Pi) sqrt(a)) )= (((2*a)/(Pi))^((1/4))*(1/(sqrt(2*a)))*(e)^((- (k^(2))/(4*a))))); and I get the Error Message " Error Unknown Operator" with a red dashed square around the first exponential (the first actual letter e)in the first expression to the left of the equal sign that i'm trying to compare. Thanks, Please anyone help
Hello, I'm a new user of Maple and I have Maple 10 now. I am able to make two separate 2D plots, one with points and one with a function, but I would like to be able to view both the points and function on the same plot. How can I do this? Thanks, Sammy
This integral |A^|^2(∫)[-infinity]^infinity(e)^(-2 ax^2) ⅆx gives me the output (|A|)^2 signum((e)^((-2 ax^2))) infinity unless i put parentheses around the -2a in the exponential to look like e^-((2a)*x^2) then i get more useful output that looks like (|A|)^2 ({[[1/2 (sqrt(2) sqrt(Pi))/(sqrt(a)),` `,csgn(a)=1], [infinity,` `,otherwise]]) Please explain the signum, and csgn(a) = 1 included in both outputs and the reason for this behavior ? new to maple thanks
help! i want to know what is the syntax and the semantic definition method of MAPLE?
Hi does it happen to you that when you evaluate an expression in maple or maplet you get this message,"Evaluate_result"? What this really mean?
