Trying to use Maple to perform some trigonometric transformations, I found a good introduction to Maple: MCS 320: Introduction to Symbolic Computation of the Department of Mathematics, Statistics, and Computer Science @ the University of Illinois at Chicago. It have some lines about the Maple function, which give that kind of informations:
>> trigsub(cos(2*x));
[cos(2*x), cos(-2*x), 2*cos(x)^2-1, 1-2*sin(x)^2, cos(x)^2-sin(x)^2, 1/sec(2*x), 1/sec(-2*x), 
(1-tan(x)^2)/(1+tan(x)^2), 1/2*exp(2*i*x)+1/2*exp(-2*i*x)]
How do i find a background curve to a graph, i have data fitted with a spline and i need to find the background curve
For example, I type in standard F=ma 5 kg * 1 m/ s^2 Maple 10 spits this back after the = as 5kg*m/s^2 rather than the more common 5 kg*m/s^2 with the divisor sign half way down the 5. And what I really want is to be able to ask for any compatible units, in this case, N for Newtons, and have N replace kg*m/s^2. I notice that there is a new [[]] format for units. When I use them, they appear in my document, not all what I'd expect. Thanks much, Rich
I'd like to have the ability to change, say, 12345.678 to Engineering 12.345E+03 12.345x10^3 Scientific 1.234E+04 1.23456x10^4 General/decimal 12345.6 fraction of varying size Are these possible? I have tried with no success... Thanks, Rich
I haven't been to mapleprimes for awhile and noticed that the "convert worksheet" option is no longer available. Are the "file manager" and "upload file" options very different from the previous worksheet converter, and are they also any more difficult ?
Can Maple 10 be used to determine if the universal or existential closure of predicate logic sentences that may or may not contain quantifiers is valid ? For example, does the tautology, equivalent and other functions of the Logic package only apply to propositional sentences ? dc
I am new to Maple 10, but have used other products for years. I tried v10 because the Maple website indicated that there was a great deal of flexibility in formatting pages. It seems to me, after a few days experimenting, that I cannot do more than put every thing in the middle of the page. Is this true? If not, is there a demo v10 sheet w/ instructions that shows how to do this? I can attach a pdf file of what I am interested in from Mathcad. Thanks much, Rich
Here is a baffling puzzle! I have two variables that look exactly the same when I print them, have the same type, but return different results when I put them into a function! Here is the unadulterated output straight from my maple window (Opps! I notice that they didn't copy into the post quite as they should... the floating 3s are actually v[1]^3 and v[8]^3 respectively. Sorry! I hope the problem is clear): > f; 3 3 c[22] v[8] + v[1] c[11] - c[22] - c[11] > g; 3 3 c[22] v[8] + v[1] c[11] - c[22] - c[11]
Hi, Please help! I'm trying to calculate the norm of a vector (3,4). Working it out in my head I get 5. Maple gives me 4. Where is my mistake? with(LinearAlgebra); A := Vector[row]([3, 4]); C := Norm(A); print(C := 4); 4 Evan
Can I display floating point numbers with a precision for inidivualy columns in a (for example) 3-column data table? How? Reply by email if you can...
MaplePrimes own Jim Herod has a wonderful set of lecture notes—accompanied by a collection of Maple worksheets—which introduce linear operators on infinite-dimensional Hilbert spaces to beginning graduate students in science and engineering. Entitled Linear Algebra, Infinite Dimensions, and Maple, these notes were developed from a one quarter course which Prof. Herod taught many times at the Georgia Institute of Technology. The notes are very concise and have been refined and improved many times over the years in response to student feedback.
Hello! How can I repress those pesty: bytes used=19294939612, alloc=37348680, time=2193.37 messages from printing? words(0) doesn't seem to have any affect and gc(0) has been deprecated (that was what a book suggested). Any ideas would be appreciated. Thanks! Susan
I'm working on some basic complex number equalities in engineering class, and was practicing converting from cartesian to polar coordinates. Maple can help by telling me if my conversions are correct by telling me whether the equality is true. For example, for the complex number: 5 + 3*I maple will verify the following: is(5+3*I = polar(sqrt(5^2+3^2), arctan(3/5))) true it will also verify: is(polar(sqrt(5^2+3^2), arctan(3/5)) = sqrt(5^2+3^2)*exp(I*arctan(3/5))) true lastly, it will of course verify transitively: is(5+3*I = sqrt(5^2+3^2)*exp(I*arctan(3/5))) true
FIRST-- I can not figure out how to enter a problem containing Set-Builder Notation? Specifically the use of the symbol in my math book "|" which means "Such That" here is an example. (a,b)={x|a<x<b} it give me an error with this form of notation Second --How do you plot on a number line, also called real line, points, line segments, rays, or lines? Third(and final for today) -- is there any way to sketch regions on the Cartesian coordinate system for problems like absolute(y)<1, y=1, or x>0 these problems will fill in areas of the plot in the quadrants? Ok after some 30+hrs of research on my own and with my fellow students I turn to you for help now. . . . Please help, and thank you.
Hi, I use maple 10.01 (and WinEdt 5.4) and I don't know how to import some graphics to Latex. Assuming that I want to have the output of plot(x^2, x=-2..3); appearing in my file (Dvi, ps or pdf).. How should I proceed? Thanks in advance for your help. JJ
