I follow the instructions in the User Manual section 5.2: Dragging to a Plot Region To use the drag-and-drop method, use the plot region created by one of the other methods or insert an empty plot region into the document. Empty plot regions can be two-dimensional or three-dimensional. Advantages of the drag-and-drop method include the ease of adding and removing plots and the independence from plotting command syntax. 1. From the Insert menu, select Plot, and then 2D. 2. Enter the expression sin(x) in an input region. 3. Select the full expression in the input region and drag it into the plot region.

with(VectorCalculus):

TangentPlane( x^2+y^2, x=a,y=b);

Error, (in VectorCalculus:-TangentPlane) 2 independent variables 
are required

However this is copied from the Help, last example, (2.8). What wrong in this example? Thanks, Sandor

greeting, i have a little trouble and getting under pressure.. i found how to "plot" circle using smartpot; i found how to get two curves into one graph by with(plots): f1:=plot(3*x^2,x=-4..4, color=orange): f2:=plot(-3*x^2+40,x=-4..4,color=blue): display(f1,f2); but i can't get things like two circles into one (i tried combining with(plots) combined with smartplot.. can anyone advise me for the case i can't find the answer? thanks

hi i know a little bit about maple, i am able to input commands for it to solve non-power series equations but i do not know how to input commands for solving equations involving the Sine Integral fucntion, Si (x) thanks in advance

Im new to maple and im stuck! How would i "Calculate an approximate real solution, correct to 10sigfig, of hte equation x^3+x-1+0"? Thanx x

Again we have the unitary and Hermitian matrices U and H related by, U = exp(i*a*H) (a) If the trace of H = 0, show that the determinant of U = +1. (b) If the determinant of U = +1, show that the trace of H = 0. Given Hint: H may be diagonalized by a similarity transformation. Then interpreting the exponential by a Maclaurin expansion, U is also diagonal. The corresponding eigenvalues are given by u[j] = exp(i*a*h[j] v/r, Guidance welcomed and appreciated

Hi guys, I'm currently using Maple 10, however, I can't seem to plot this function: >implicitplot(cos(x+y)=xy^2,x=-2..2,y=-2..2); When I press enter, it just says: "Error in implicit plot could not evaluate expression." Anyone know?

How do I define a function on different intervals? For example, how to define y(x): y(x) = f(x) for x=a..b g(x) for x=b..c Hope anyone can help

Using maple 10, when I store say a 15 x 1 matrix I get the placeholder (1..15 Vector[column], Datatype=anything....) When I close the document and open it back up, all af the data I typed in is gone. What's up with this?

I am trying to gain some experience in maple coding, frankly I'm terrible so a tutor has kindly set me some tasks. He wants me to write a procedure for solving any tridiagonal system of equations. Here is his brief: Write a procedure to solve a given tridiagonal system of equations. Use lists to input the coefficients and do NOT use matrices and/or Maple arrays. The procedure can then be called at every time step. This will also be more involved. After a bit of research I know this is the starting matrix: b1x1 + c1x2 = d1 a2x1 + b2x2 + c2x3 = d2

I am trying to find a easy way to use analytic functions with matrices. For example A:= 2x2 matrix (that is diagonalizable) then cos (A) = P L P^1 where P is the matrix made of the eigen vectors and L is the matrix of eigen values along the main diagonal. While I can work these problems by figuring the parts (P L P^1) I would prefer to find a way to be able to just write cos(A). I figure there is a syntax that I am failing to use properly to use this function with a matrix input. Any help would be appreciated.

hey i have the equation y=3X^4+2X^3-15X^2+13X+3 I need to find the (x,y) values of the maximum and minimum points to 3sf. im not too good with computers can anyone help me

Dear Sir: I am still a novice to use the maple. Please give some advice for the following code. Expecially, I try to construct the final P(3x3) matrix. In the for-loop, normalized vectors are generated. Then, those are converted into a matrix. But, I do not know how to write a code. restart: with(LinearAlgebra): interface(displayprecision=4): mass:=Matrix([[m[1],0,0],[0,m[2],0],[0,0,m[3]]]); stif:=Matrix([[k[1]+k[2],-k[1],0],[-k[1],k[1]+k[2],-k[2]],[0,-k[2],k[2]]]); m[1],m[2],m[3],k[1],k[2],k[3]:=4,4,4,4,4,4; msri:=simplify(MatrixFunction(mass,sqrt(x),x)^(-1)); mass2:=msri.mass.msri; stif2:=msri.stif.msri;

x=3/2 y-1/2 Three over two times y minus one over two for the previous question.
