MaplePrimes Questions

This is surely the equivalent of using an elephant gun to go after an ant but in any case. Could someone tell me how to sub in four values for y, -2,0,1.5 and 3, one at a time in this equation: 3 1 x = - y - - 2 2 I am only using document mode but can not figure out how to automate this type of problem. I am able to manually sub in the value but I am too lazy to do all that work. Also is there any way to show the steps of the solution and not just pop out the answer?
How do I graph the first 30 minutes of this problem? T = 32+127*exp(-.3456*30) Also, when this is graphed, it is supposed to show a horizontal asymptote.
I am trying to populate a matrix using a nested for..from loop. The Maple statments below only populate the first column; any suggestions? > for i to 45 do for j from 0 by 5 to 45 > do A[i, j+1] := evalf(EllipticF(sin(i*deg2rad), sin(j))); > end do; > end do; Thank you for the assistance.
Hello, I am given a question in the form f(x)=x^delta sin(1/x) if x does not equal zero,and f(x)=0 if x = 0. the question goes on to say, where delta > 0, we know that f is continous at x=0, but is differentiable at x=o only when delta > 1. it asks me to use maple to provide evidence for this using MAPLE,s graphing features. I am not sure how to input this into MAPLE. Could someone please help? thank's a bunch I think i posted this in the wrong section before.

how do i determine the derivitive of y=lnsinx-(1/2sin^2x)
I need to plot about 44 points on an X-Y graph. All the X coordinates are given (imported from Excel) as a list. All the Y coordinates are given as a separate list. For example (roughly this is what the order of magnitudes are of the X and Y variables) X:=[380,4000,4067,...,5789] Y:=[10, 35, 56,...,82] So plot (380,10) (4000,35) (4067, 56)... (5789,82) I will worry about curve fitting and all that stuff later. I would first and foremost like to see Maple understand my data and plot it.
dear Maple Masters, i have a plotting problem about the equation |x|+|y|=5. the plot shows strange corners of the rectangle, which is absolutely incorrect as far as i'm concerned. am i wrong? or is this a bug?
Is there a way to evaluate the format of the responses and prevent the grading? In particular I want to provide feedback to students who used a comma instead of a dot in a numerical response. At this moment Maple TA cannot deal with a correct response except for the incorrect format (0,93 instead of 0.93) and evaluates the response as incorrect. There must be a way to prevent students to grade as long as there are comma´s at places where there should be dots. Harry Garst
Is there a 'search and replace' method to replace all comma´s by dots (as a decimal seperator). For example 0,78 into 0.78. At this moment several students responses were graded as incorrect while the only error they made was to provide a response using a comma instead of a dot. I can export the data file and use another program to score the responses, but there may be a much more efficient method to modify the responses. Harry Garst
Hi guys, I need to simplify tedious expressions involving products of fermionic creation/annihilation operators. I loaded the Physics package, and defined the fermionic operators c[i,spin] and C[i,spin] where i=1..4, spin=1..2 My first concern is that c[i,spin].c[i,spin] doesn't return 0, while AntiCommutator(c[i,spin],c[i,spin]) does... I don't get it. Although when I apply c[i,spin].c[i,spin] to some ket it does return 0... I'm a bit lost. Any idea?
All I have a simple Alternating Series - that will not come up with a convergent result in Maple 11. Here is the problem ... Is ... this alternating series convergent or not ? sum((-1)^n/ln(n), n = 2 .. infinity) Application of the Alternating series test says YES ... but Maple does not give a result. Thanks,
donnie
LINK to example file with Alternating Series test showing convergent test to be positive.
So I get this to calculate correctly: sum(1/n, n = 2 .. infinity); And the result is infinity - which is obviously correct. but the following does not give me a result ... sum(1/ln(n), n = 2 .. infinity); what is the trick - do i need to assume something here ? thanks, dp
I am solving a constrained maximization problem using the Lagrangian and getting back an empty set of solutions, i.e.: solns_LSW:= How do I go about diagnosing why Maple is having difficulty finding solutions? (Once I know that, I would of course also like to know how, if possible, to change the set-up so that Maple might actually find the solution(s)!) I can see that the Lagrangian becomes non-concave for cases where lambda2>p (p is one of the variables I am solving for: there are two, s and p -- see attached worksheet). This would clearly be the case for, say, p=0 optimal (which I have reason to believe it is, based on some numerical simulations I ran).
Dear all, In the attached file I try to solve expression Y for p. As Y includes dCS(p)/dp, the solve command produces an error message. I do understand that Y can't be solved for p since expression dCS(p)/dp is not fully defined. However, the result I am aiming for is simply: p = -(1/2)*(dCS(p)/dp) (with p simply being a funtion of dCS(p)/dp) Which command leads to this result? I haven't found it in the help section.
