Why doesn't 'ln(e)' simplify to '1' in Maple 12.02?

The problem arose from trying to simplify the solution of an ODE that contains a combination of exponentials, logarithms and powers. Maple refuses to simplify, whereas I can easily read the simplified answer. Maple seems to ignore the simplest of algebra concerning power, logarithms and exponentials.

what is the general sum formula for the following seires (we may notice from these few terms it has a pattern)

From menu, Insert -> Table...  is there code to extract values from specific cells in the table?

I so thankful for your help. Please help me expressing this expression compactly is there any pattern here?

I have a mapleTA question that blocks students from starting a mastery assignment until I tell them how to do the problem. But some students are gaming it but finding out the problem from an earlier section. I want to game back by making the answer change depending on the wall clock, that is the section they are in. To do so, I need a clock function to tell the time. Since I can call maple inside mapleTA, a maple solution will also work.

Hello,

I want to generate a source component,namely,acceleration function,y(t)=(1/2)*t^2,where y(t) is output of the component. Is there any way to generate it?

By the way,I find a component,named 'Real Expression',which located in Signal Blocks\Sources\Real. I thought it may solve my problem,but after reading the help document,I felt the description was too simple to understand. Can you give me an example of how it can be used?

Thank you!

Does anyone have any idea why I'm getting this plotting error? This should be working!!! Ahhh.

Hello,

I need some help with plotting the function with varying variables lambda and m ( varying from 0.1 to 1) which subject to the mutual constraint.

My function is:

> d:=(lambda, m) -> (0.1281008386e-3*m*lambda*(20.004936*lambda+21.004936*m+1)^2/(lambda+m)^2+0.1281008386e-3*(21.004936*lambda+21.004936*m-m*(1-lambda))^2/(lambda+m)^2)-(0.2690752038e-2+0.2690752038e-2*m*lambda);

The constraint is:

Hi all,

I need to define a state machine in MapleSim. A Maple procedure would help to solve this issue. How do I include a Maple procedure in my MapleSim model?

I am looking forward to your answers.

Is there a way to have interval arithmetics for complex inputs
(maple seems to name that range arithmetics in the help)?

x:=Pi/5;
shake(x);

              INTERVAL(0.628318529462 .. 0.628318531974)

shake(x*I);

    Error, (in evalr/shake) not a real number

Hi all,

I have gone through the help pages in my Maple 12, but cudn't really solve for roots of more than 1 pollynomial equations in parametric form. (I saw roots,parametric pollynomial function etc. & many more but cudnt do it with success).

my equations are coupled like, for example,

axy + bx - c*x*(x+y) = 0,

dxy + ey - f*y*(x+y) = 0,

etc. and I need the roots (x,y...

sorry for posting the same question again. reason: the equation no. (2)

Thank you so very much for your help.

I was to solve, means find y as a function of x, equations like the following

y(x) = 7/8 * x + 1/2 * int (x*t*y(t)^2,t=0..1)

or

Dear guides

I have an equation: "eq := Pi-arcsin(sqrt(2E)/sqrt(1+E))-arcsin(sqrt(2E)/sqrt(2+E))-2*sqrt(2E)=0;

when I use "solve" maple say: "Warning, solutions may have been lost" and get a bad result. How can I ontain a better answer?

thanks.

How could I have information of serial of a hard disk in Maple? Thank you very much!
