Integrals...

int((4*x-3)^3, dx) Tried to use Maple straight away to integrate the above. As it turned ou the answer was wrong.Does this mean that I have to solve it by way of substition Curious

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

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...

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

Maple TA 2.5 {no access on Linux Server}...

Hello Dears, Although I have been worked on Maple TA in LAN's

Getting the username within Maple T.A....

Hi, does anyone know if it's possible to "get hold of" the username of the student taking a test in Maple T.A.? That is, is there a variable that contains this string? This could prove useful for personalising question content (think of individual seeds for random number generation, or keys in cryptographic contexts). We would love to be able to (predictably) provide a customised question for each student by somehow hashing up the username, and writing a question which uses that variable. If there's an alternative to this I'd very much like to hear about it: in essence we wish to grasp hold of something that's unique to the student who's logged in.

Assumption not working with PDE...

Hello! I have the following PDE: PDE := { diff(alpha[1](u, v), u) = -I*exp(I*u)*beta[1](u, v), diff(alpha[1](u, v), v) = -I*exp(-I*v)*beta[2](u, v), diff(alpha[2](u, v), u) = I*exp(-I*u)*beta[2](u, v), diff(alpha[2](u, v), v) = -I*exp(I*v)*beta[1](u, v), diff(beta[1](u, v), u) = (1/8*(I*exp(-I*v)*alpha[2](u, v)+(2*I)*beta[1](u, v)+(2*I)*exp(-I*(v+u))*beta[2](u, v)))*(a-1)-(1/8*(-I*exp(-I*u)*alpha[1](u, v)-(2*I)*beta[1](u, v)+(2*I)*exp(-I*(v+u))*beta[2](u, v)))*b, diff(beta[1](u, v), v) = (1/8*(I*exp(-I*u)*alpha[1](u, v)+(2*I)*beta[1](u, v)-(2*I)*exp(-I*(v+u))*beta[2](u, v)))*(a-1)-(1/8*(I*exp(-I*v)*alpha[2](u, v)+(2*I)*beta[1](u, v)+(2*I)*exp(-I*(v+u))*beta[2](u, v)))*b,

Differentiating with Maple...

How do I, with Maple, differentiate the following y = (x- 1)^2/x Curious

Differentiating with Maple...

Hi I wish to thank all those who generously helped me with my last prob. Now I have another. These are mainly related to the use of Maple with the application in question. How do I use Maple to differentiate the following: A=pi.r^2. I am not doing homework. I can do it without MAPLE. However I want to master Maple. Never used it before. The answer I get with Maple is different to the one I get myself: 2pi.r Curious Please replace this text with the link to your file. The link can be found in the File Manager

Elliptic Integrals...

The paper that Wayne Bell is using dates from 1962, so it’s not surprising that Professor Robert Israel found its format for elliptic integrals differs from those of Maple and Mathematika. Indeed, it differs from those of Professor LM Milne-Thompson (circa 1960) in A&S chapter 17. It belongs to an earlier era, though - according to an antique textbook of mine (circa 1930s) - the format would have been reversed, i.e. F(k,beta) and E(k,beta). It’s curious that Maple adopted a format, resembling but differing from that of A&S. Does anyone know the reason?

Formatting equations...

How do I format a variable with the superscript bar over the variable?

Older Maple Finite Element Method Package...

Fedderik van der Bos created a worksheet for the Finite Element Method that is available in the download section for engineering applications; problem is, it uses a maple package (FEM) that is not posted on the site. The application is dated 2000. Does anyone have a copy of this package?

Pie Chart...

Hi, I'm trying to do a piechart. the following code generates one alright but I have no idea how I can make the labels be outside instead of inside the piechart. any ideas?? with(Statistics); PieChart([England = 341, Spain = 237, Germany = 93, France = 91, Unknown = 56, Wales = 40, Ireland = 39, Sweden = 35, Russia = 31, Other = 244], color = orange .. green); thanks Antje

block toeplitz matrices...

Does anyone know a way to get Maple to take advantage of the type of matrix you are giving it? I have a block toeplitz matrix and am using Maple to find the eigenvalues and eigenvectors. Thanks in advance :D
