Dear All:

I have a curve about mosfet Coss Vs. Vds . the detail math relationship can be found in the following picture:

Can anyone fitting this picture by simple math function.

PS: pls don't considering piecewise function

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

I'm creating a table of random math problems for my daughter to print out. How do I get more columns?

a := rand(1 .. 15):b := ["+", "-", "x", "/"]:

for i to 15 do print(cat(a(),b[rand(1..nops(b))()],a(),"_____")): print(``):end do;

13x4_____

Hi all, I found that the expression:

(2x+7)/5+(6x-3)/3

automatically simplifies to

Is there a function that will return

which is one fraction, instead?

I've made exam questions for students that they have to answer by doing some calculations in Maple.

I would like to let them copy the commands they used to a Maple TA text field.

However, the standard worksheet in our computer lab uses 2-D math. Copying this 2-D math to Maple TA works fine with "paste as plain text", but copying 1-D math also works with ctrl-v in Maple TA, which is more convenient for students under stress.

Since I am not allowed change...

Hi I teach in a high school. Basically I have found that if I ask a question like: Factorize fully (x^{4}-y^{4}), and use a MathContainer for both the question and the answer (to be filled by students), I can't find a way to see whether the students have fully factorized the expression. Suppose (x^{4}-y^{4}) is in MathContainer1 and MathContainer2 is to be filled in by students. Using the code:

if GetProperty('MathContainer1','expression'...

Hello Everybody.

Im new to Maple, so i have a couple of questions. In the last few days I have learned the basic of Maple, and now i would like to solve an differential equation.

The Math question is:

Enter the solution of differential equation:

In the link i have put in the informations from the math question.

HI,

at first I have to admit, that I'm totaly new to maple and have only few experience with the programm.

That's the problem. I've got an old maple-code which I want to rewrite in the 2d-Math-syntax. In the code there are a lot of variables of the type "numerical integer" with a form like

"rho_a"

"N_A"

....

--> with index in the name

It's a code for a physical-/chemical- process so the...

It is the mathematica code for bifurcation diagram of the model that i am working with now. is there anybody who can translate it into maple code? or does anyone can help me with making a bifurcation diagram for such a ODE system in maple??

Thanks in advance

I've submitted an application to the Application Center: An Epidemic Model (for Influenza or Zombies). This is an interactive Maple document, suitable for instructional use in an undergraduate course in mathematical biology or differential equations, or a calculus course that include differential equations. ...

I've submitted an application to the Application Center: Great Expectations. This is an interactive Maple document, suitable for instructional use in an undergraduate course in Probability. The mathematical content is related to the Laws of Large Numbers and Central Limit Theorem. It requires no knowledge of Maple to use.

I'm doing a math assignment for numerical methods and I had to answer a question - solving Newton's method in maple to submit. I need to solve the question to an accuracy of 10^-5. I don't have access to the software right now as I only have it on the computers at our school, but I did take a maple course in my first year of university and have some experience with it. I wrote up this formula, but I'm not 100% sure if its correct. Could someone...

I have a derivation to do for my PhD thesis, and it is long and tedious. It is essentially a case of splitting sums, making substitutions and then simplifying. I believe maple can do this for me, but have not found how yet. Any suggestions would be more than welcome. I have done this for a third order problem (three nested sums) and the derivation runs to many pages. I now need to do so for the 4th order problem, and it is a more than daunting prospect

Good afternoon

i have problem when i am using components.

i want to solve a determinant equation and show in MathContainer4

thank you for your help

Hello mathematicians :)

I have a problem finding the inverse of the following 12x12 matrix:
