In Vector Calculus there are excellent commands for finding the normal vector to a curve (PrincipalNormal and TNBFrame) but none for finding the surface normal vector. It is possible to display the surface normal vector using PlotPositionVector's normal option, but this is good for visualization only, and the vector can't be used for further calculations.

Am I missing something, or is this really missing form the package?

Hi,

Is it possible in Maple to output a complex number using j (or i) instead of I ?

thanks,

Hello,

I wish to enter in the math dot operator but I can't find the way to enter it in the document mod. I also searched the help and did not find a way.

all I want is to enter dot(varphi)

thanks

Hi

I have used the series command to expand sin(x) as a Taylor series about x=0, as follows:

In Maple 14

with(epsilon); > f:=[(x-u)^2+(y-v)^2-1,v^2-u^3,2*v*(x-u)+3*u^2*(y-v),(3*w*u^2-1)*(2*w*v-1)]; > printlevel:=2:

              ...

When I type a operation in maple such as limit, derivative, integral... then I enter. It only show the result. but I want it to show clearly  each step of  solving. What should I do?

Thank

I would like to see all the solutions for the following:

int(1/(a-(b+c)*t),t);

but the result only gives

(ln((-b-c)*t+a)/(-b-c)

For example, I can imagine that if b=-c in the integrand that the solution should be

t/a

and not undefined as it would be by substituting b=-c into the Maple result.

I tried

int(1/(a-(b+c)*x),x=0..t,AllSolutions);

but I didn't find that this gave the answer I was looking for either.

In 2D Math of maple 15, when I type a operation  then I press Enter, It show the result below. But I want it to show the result next to the operation behind the equal sign. How should I do ?

for example:

instead of show :

7+9;

16

I want it to show this :

7 + 9 = 16

Help me!

Thank you

I want to be able to check my work and see if I have indeed got the correct mapping.

Say I want to find the image of a circle |z| = 3 in the complex plane under the mapping: w = 6/z

How would I do this?

Thanks

Dear Maple users

I am experiencing a strange problem with my clipboard. I am using Ducument Mode and when I am trying to copy part of my document using Ctrl+C and place it in the same document using Ctrl+V, then sometimes things are not being copied properly as can be seen on my image below. It is as though the clipboard doesn't pick up the fomatting. When I restart my computer things works fine until a certain point when it stops working. I hope someone can...

Hello, everbody!

1)Dr:=[[1,5],[2,6],[4,7]];

2)Y:=proc(i) Dr[i,2] end proc

3)ty:=proc(i) Dr[i,1] end proc

4)P[X](omega) = (1/2)*{(Sum(Y(j)*cos(omega*(ty(j)-1/(2*omega*tan((Sum(sin(2*omega*ty(j)), j = 1 .. N[0]));

1, 2, and 3 are known. I want to count 4, but I don`t know how I have to do this. Please help me.

Thanks...

These are my first steps with the maple software and there is the following problem to answer.

a) I have to define a sequence L who is dividing a interval between [0,2*pi] in 20 sub intervals.

    The output of the different values should be in decimal numbers.

how can i solve pdes of the following form in maple

[tex] tc(t,x)\frac{\partial a(t,x)}{\partial t} - ta(t,x)\frac{\partial c(t,x)}{\partial t} = a(t,x)c(t,x) + t(a(t,x))^2 and be able to find both functions a(t,x) and b(t,x)
