a bus travels 200 km at a constant speed. a car travelling 10 km/h faster than the bus, completes the same distance in 1 hour less than the bus. (1) how many hours does the bus take to travel the 200 km? (2) what is the speed of the car?

I am trying to use the EllipticE and EllipticF functions in an expression. The proper function call is EllipticE(z, k) where z = algebraic expression (the sine of the amplitude) k = algebraic expression (the parameter) I get exact agreement for 0 <>< value="" value=""><><>

I have a very long Equation and I need to simplifying it, I don't know how to use Maple is it possible one helps me how to do it? or simplifying it for me. Can Maple do it and how it will looks like?? my equation is d/h = ((((T / SK) + (T * -0.390527)) / (((T + -0.421559) * (SK + (SK + ((SK / (SK + (((T * -0.39954) + (SK + (T / SK))) + SK))) + SK)))) / T)) * -0.376824) If one can help to restructure it and give a simple one from two parts only, it will be so nice

This isn't specifically Maple-related; but mathematics-related; related to Linear Algebra and Modern Algebra. While reviewing Linear Algebra; I ran across the concept of "Similar Matrices"; which are defined as: if A,B are nxn matrices and there exists invertible nxn matrix P such that P^(-1)*A*P = B then A is similar to B The payoff was: if A, B are similar then they "have the same eigenvalues" (the characteristic equation is same for both A and B). (Here we are talking about the group of invertible nxn matrices, with operation matrix multiplication) --

The command "latex(expression)" attempts to generate LaTeX commands that will recreate the expression in LaTeX. For example; latex(%) will try to generate LaTeX commands to recreate the last output from Maple. Let's say I had just entered the Maple command to display an integral; for example: Int(Int(Int(rho^2*sin(phi),rho=sec(phi)..5*sec(phi)),phi=Pi/6..Pi/3),theta=0..2*Pi); If I would like to put that same integral in a LaTeX document; I could enter the following command: latex(%); Which, in Maple 9, returned: \int _{0}^{2\,\pi }\!\int _{1/6\,\pi }^{1/3\,\pi }\!\int _{\sec

Why not put the entire Maple help-system online? I mean, as html. No served .mw or plugins. No huge .pdf downloads. Just the goods, one page per routine, that load and render fast for every half-decent browser. No registration and login would be nice too. Consider the competition's sites, here and here. Wouldn't that be another...

There's an interesting set of posts on comp.soft-sys.math.maple about post-processing .eps plot output from Maple. Here's a link via Google Groups. The author's ideas revolve mostly about processing tickmarks and subtickmarks and replacing them with symbols. The claim is made that it's harder (or impossible) to do some things in Maple for .eps output that are possible in Mathematica or Matlab. I haven't yet tried or looked hard at the posted code, or verified the claim.

I'm a relatively new user of Maple, and I use it to teach high school mathematics. I've noticed that when Maple expands an expression like (x+y+z)^6, the terms come out in a different order each time the operation is done. If 6 students do it on 6 computers we get 6 different orderings. Is there an explanation for why Maple's algorithm does this that would be potentially comprehensible to my students (they are quite curious)?

When I use the GUI to produce the graph of y = 5x^2/(1+x^2), the graph is cut off in the exported .eps. Precisely, Type In: 5x^2/(1+x^2) , Right click- plots-2D plot, then Right-Click on graph, export as .eps. Open the resulting .eps file and the graph is truncated at around x=3. ?(Exporting as .gif or .jpeg seems to work here). However, plot( 5x^2/(1+x^2), x=-10..10) produces the correct result upon .eps exportation I thought this might have with smartplot vs. plot, but 2D plots constructed with plot builder are truncated as well.

It seems to me that I found a tip (I am a beginning user) In running these three commands in Maple 10, one gets: > sum(1/(n^4+1), n = -infinity .. infinity) sum(1/(n^4+1), n = -infinity .. infinity) > sum(1/(n^4+1), n = 0 .. infinity) 1/4*(Sum(_alpha*Psi(-_alpha), _alpha = RootOf(_Z^4+1))) > sum(1/(n^4+1), n = -infinity .. infinity) 0 The last answer is obviously wrong. In other similar experiments, Maple gives the answer -infinity to the last expression, which is also wrong. Could somebody comment on this phenomenon? Many thanks in advance.

Just wondering... what's wrong with the following command? > plot( cot(x), x=-Pi..Pi, view=[-Pi..Pi,-3..3] ); -- Regards, Franky.

i need to solve a set of linear equations of size 7000x7000 using 128 digits, the system is sparsed. which of the "options" in LinearAlgebra[LinearSolve) is the the most efficient? is there more efficient builtin procedure for such computations? thank's

Hello. I wanted to report problem with installation of Maple1102LinuxUpgrade.bin in Gentoo Linux. My attempts to install it failed with the following error: peter@camobap ~/tmp $ ./Maple1102LinuxUpgrade.bin Preparing to install... Extracting the JRE from the installer archive...

Should we have a mark to indicate Maplesoft employees? Maybe a special colour of leaf or something. I'm not sure if this is needed or even a good idea, I'm just asking the question.

A new version of Plouffe's Inverter was announced by its author today in the usenet group comp.soft-sys.math.maple . That usenet posting gave this link to maple code for the inverter.

It also said this, "As usual, I would like to mention that this program is FREE and can be distributed at will, I just wish that the source is mentioned. Simon Plouffe"
