I've written 2 long nonlinear symbolic equations with 2 unknowns in Maple, but it doesn't solve it and says:"Kernel connection has been lost".

I have attached my worksheet to this message; what should I do?

I have an assignment that I am suppose to be doing in maple, I am suppose to plot the function f(x)=e^(x/3)sin(2x) for abs(x)<=2.... for part of it...

Ive tried multiple things in maple such as plot(exp((1/3)*x)*sin(2*x), abs(x) <= 2) but it keeps throwing me an error, any insight on how to get tis graph plotted would be great.

I want to evaluate - del(psi)/del(x) analytically in MAPLE. I wrote the following lines for the purpose :

deltat := proc (x) options operator, arrow; lambda*x^m end proc

Gr := proc (x) options operator, arrow; g*beta*deltat*x^3/nu^2 end proc

xi := proc (x) options operator, arrow; g*beta*x/c[p] end proc

eta := proc (x) options operator, arrow; (1/4)*y*4^(3/4)*Gr^(1/4)/x end proc

psi := proc (x, y) options operator, arrow; nu*4^(3/4...

How do I prevent that maple scrolls through the worksheet and stops at the bottom when I want to execute the  whole worksheet. If i want to execute the whole worksheet I just want to stay at the same place in the worksheet and I also don't want to expand previousily closed sections. I use document mode. Thanks in advance

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
