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

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

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.

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,

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

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

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?

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

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?

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

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

Hello, In Maxima integrate(5-(5-x)^2, x) gives... -x^3/3 + 5*x^2 - 20*x However, in Maple 11 int(5-(5-x)^2,x); gives 5*x + (1/3)*(5-x)^3 They're different by 125/3. Why is this? Ty

I am trying to plot an equation containing special functions - namely, elliptic integrals. The goal is to plot equation (16) of the attached file. Any suggestions/guidance is appreciated. View 4865_Equation_16.mw on MapleNet or Download 4865_Equation_16.mw

I was wondering if Maple can read an inputfile the way tecplot can, or at least plot a huge list of coordinates WITHOUT using the pointplot command (it will take me to long to put all of my coordinates in pointplot's correct input format). I have a list of about 5000 coordinates (x and y) and I want to see y vs x in a 2D graph. Any help is GREATLY appreciated Thanks.

Is there a way to choose the colours? If using it with 'implicitplot' on something like y - x it gives brute red and yellow ...
