Maple evalution rules at function definition

I am trying to define a function, A, which has a function call, B, in its body. The function call to B is independent of input parameters of A. Maple does not call B at function definition. Is there any way to force it to evaluate call to B at…

Eliminate variable in Maple

I tried to search, and found some answers that were sort of relevant. However I could not get it to work. So, I have two equations $x=f(\xi)$ and $z = g(\xi)$, both being affine, thus invertible. More precisely the equations…

Algebraic extension by $\sqrt{-7}$

In trying to find the Galois group of a polynomial, I am trying to see if adjoining $\sqrt{-7}$ can split the polynomial but entering factor(x^2 + 7 , $\sqrt{-7}$) is invalid. How can I accomplish this?

Maple: solve with a variable or fsolve without variable return different result

I've encountered a very strange issue with Maple. Hopefully to get an answer from here. The result returns differently with solve and fsolve after/before a variable is given a certain value. See attachment and/or PDF exported from Maple The result…

How to calculate power of a tensor field in maple?

Let $\alpha_i$ be linearly independent $1$-forms and $T$ a $(1,1)$-tensor such that $$T=T^i_j \alpha_i\otimes X^j,$$ where $X^j$'s are vector fields dual to $\alpha_j$ in Riemannian manifold $(M,g)$. Then How to calculate $T^2=T\circ T$ in maple…

How to plot two functions together in Maple

I'm given two functions (a surface and a tangent plane), and I am required to plot them together in the same graph in Maple. The surface is $$x^2y^2+y^2z^2+z^2x^2=15$$ and the tangent plane is $$z=\frac{9}{2}-\frac{5}{4}x-\frac{5}{4}y$$ I have used …

Plotting surface within a box in Maple

I'm given a surface $$S=x^2y^2+x^2z^2+y^2z^2=9$$ and I am being asked to plot the part of this surface which lies within a box with the dimensions $$[-10,10] \times [-10,10] \times [-10,10]$$ I understand how to plot the surface, but I'm not sure…

Understanding how to use implicitdiff command in Maple 17

I am given a system $$\left\{\begin{matrix}xy^2+zu+v^2=3 \\ x^3z+2y-uv=2 \\ xu+yv-xyz=1 \end{matrix}\right.$$ which defines x, y, z as functions of (u,v) around (1, 1, 1, 1, 1). I've been asked to compute $$\frac{\partial y}{\partial u}(1, 1)$$ and…

Trouble Plotting Mobius Strip in Maple 17

I'm quite new to Maple, so forgive me if this question seems a little trivial. I'm trying to plot a Mobius strip with the parametrization $$\left\{\begin{matrix} [1+tcos(s)]cos(2s)\\ [1+tcos(s)]sin(2s) \\ tsin(s) \end{matrix}\right.$$ with the…

Changing colors of entries of a matrix in Maple

I need to make distinction between certain entries of a matrix that are identical. The only practical solution I can think of is to use different color. Can someone please tell me how to modify the color of individual entries of a matrix in Maple? I…

how to find derivative

It is necessary for me to find $\Delta^2 u=u_{xxxx}+u_{yyyy}+2u_{xxyy}$ where $u=u(r,t).$ I tried by the following but got an error in Maple. $$x:=rcos(t);~y:=rsin(t);$$ then tried to find $$diff(u,x$4)+diff(u,y$4)+2diff(diff(u,x$2),y$2).$$ but…

Error, (in sum) summation variable previously assigned

Assume that I have a function like this func1 := proc (a) return sum(i, i=1..a); end proc; This function works as long as I don't define a global variable $i$. If I do that, every subsequent call to func1 returns this error: Error, (in sum)…

Maple zeroth entry of list or some other data structure?

Is it possible to change the structure of a list such that the $1$st element becomes the $0$th? That is, if $x$ is a list then $x[0]$ calls the first element of $x$. I am writing some pseudo-codes in Maple for my Numerical Analysis course, and the…
