How do I create RightOverArrow with subliteral?...

Asked by:
I want to create a Maple symbol consisting of a subliteral with a right arrow over it. If I create the subliteral with the third entry in the Layout Pallette and then use the second entry in the Accents palette to add the RightOverArrow, then I get the message "Error, invalid overscript". Example: Subliteral from Layout Palette, type "V", tab, type "x", Highlight the entire entry and select RightOverArrow from Accents palette, type

Inequalities...

Asked by:
How do I graph inequalities. A simple example would be graphing y>x-2 where the area above the line y=x-2 would be shaded. What I really want to do however is check my work for the graph of: |x-y|+|x|+|y| where | | is the absolute symbol.

Asked by:
Is this thing called Interval Math? Can Maple do it? Is this thing called Interval Math? Can Maple do it? I am not about if this is called Interval Analysis. The thing in my mind is that I know my Monte Carlo simulation yields a result with an error tolerance of 1e-5. And I wrap that MC simulation component into a more complicated expression and form a function, I want to know the error bound of the whole function involving the MC component. Can Maple do this? The same applies to analysis about round-off error. If I know a sub-expression has a round-off error of 1e-6, what should the error of the main expression involving this sub-expression be?

Trig and Maple 11...

Asked by:
I am using Maple 11 student and am in a trig class. Well we are working on right triangles and are using the six trig functions to solve the triangles. How do I input a sin() etc... and get a correct response. I also need to know how to put a degree mark after the sin(26) number in the parenthesis. I know this sounds simple but I cannot find in the help areas where to do this. I guess I am looking for the DMS characters, degree, Minutes, Seconds. For some reason when I input a sin(), cos(), I do not get a correct response compared to my Ti89 Titanium calculator. and also how do I doe csc, sec, and cot. Do I just input sin^1 etc...?

What's the use of code generator?...

Asked by:
For trivial expressions, we don't need automatic code generation. For complicated expressions, code generator creates lots of temporary variables and the performance is not far from optimal. Once I generated a C program using codegen with 500+ temporary variables and I put that function into a numerical integral as an integrand. The result was very unstable - the integrals are often NaNs. On the other hand, I also convert Maple expression manually into C program which has exactly the same functionality. The result was correct, no NaNs in the integrals at all. So what's the use o

Wrapping code in a procedure...

Asked by:
Hello all, I want to turn the following piece of code into a function of sorts by wrapping it in a proc. When I attempt to do so exactly as given in the below sample, 2 error messages are returned: The first is an 'Error, unterminated procedure' and the second 'Error, unable to parse'. > restart; with(LinearAlgebra); > func:=proc(params,a,b) eta_f:=params[1]: eta_s:=params[2]: eta_w:=params[3]: eta_int:=params[4]: omega:=params[5]: G:= params[6]: u[0]:= params[7]: params[7]: n:=a+b: Arand:=RandomMatrix(n,n):A:= Arand-Arand: end proc; To state my problem in it's completeness; For simplicity I have only included an excerpt of my full input - which runs fine before the introduction of 'proc' - but I encounter identical problems to that outlined above throughout. As such I assume a solution to the above excerpt can be applied generally.

Integral Representation for Mathieu Functions (?)...

Asked by:
Hi all, I am posing a question that has plagued me since I studied these in a Dynamical Systems course a couple of years ago... Is it possible to get an integral representation for the (angular) Mathieu Functions (AMF's) - via generating functions or any method? Consulting Ambrowitz and Stegun, and searching through recent papers the closest I came to finding such a result was one that (paradoxically) gave the integral representation of the AMF's in terms of itself (it appeared in the integral kernel). So I was wondering if anyone could do any better or clarify this. John

I cannot evaluate a limit......

Asked by:
I want to evaluate the limit as sigma=0 of the integral from -infinity to +infinity of V(t)*f(t) where f(.) is the normal density. I think that I must obtain V(mu) but I only get: "lim sigma->inf of integral etc etc. " The "commands" that I did use are: restart; > MyFunc1:=(t,sigma,mu)->int(V(t)*1/2*2^(1/2)/Pi^(1/2)/sigma*exp(-1/2*(t-mu)^2/sigma^2), t=-infinity..+infinity); >limit(MyFunc1(t,sigma, mu), sigma=0); Probably I am doing something wrong, because I am almost sure that MAPLE can do it. Could somebody please point my mistake or suggest any hint? Thanks a lot. JV

trigenometry help...

Asked by:
I am a nursing student and do not understand math very well at all. i need help with 5 math problems . I would greatly appreciate any help out there. thanks in advance.(they are multiple choice problems.) 1) Convert this relationship to a form which has no trigonometric relationships in the answer, just numbers. [2*(tan of 15 degrees)]/[1 - tan^2 of 15 degrees] a) sqrt3 b) 3 c) (sqrt3)/3 d) 3/(sqrt3) 2) Choose the answer which completes the identity below.( i believe this is D, am i correct?) (The square of the tangent of x) + 1 = ? or alternatively written in symbols this is [tan^2(x)] + 1 = ?

How can we find intersection of a cone and a dynam...

Asked by:
Hi, i would like to put a question. suppose we have a cone, and we want to find whether a line will intersect the cone or not, how will we find this? A more challenging question would be: if the line is changing due to the movement of originating point, how would we find its intersection?

An unexpected error to a simple problem...help ple...

Asked by:
Hi everyone, First things first, I really enjoy reading this forum and have found it quite helpful; kudos to the experts who make this a very valuable resource. That being said I've been using MAPLE 10 since its release and recently began working in the Worksheet mode rather than the Document mode - the benefits of which have been mentioned in previous topics and explains my shift. This has lead me to a problem which makes no sense to me and I could use a little help on. Essentially I have a list of values acquired from a strain gage signal (non-integer floats) and wish to select a value within the list closest to 10,000, retrieve the associated index for it and create a new list up to that value for further calculations. Here is the input (SG1 is my list):

MathMLViewer Statement...

Asked by:
I uploaded a code intended to create a step by step solution to find the area of a triangle, starting with the formula, substitution, and evaluation of that statement. However the value of b[3], the evaluation part, is placed infront of the statement instead of the last statement. I have been looking at the code for weeks but I get no where. Maybe a second eye will see what is wrong with the code. View 690_Howto.mw on MapleNet or Download 690_Howto.mw
