i want an exaact answer(numeral) of an equation but I can't maple answer a realation that include sin,cos,root,z how can i simplify that to a number

Hi all.. Just purchased the maple 16 today. When i tried to enter a few equations, i relised that equals sign does not work for the equations. I tried '' ctrl+= '' but the letters on the screen get minimized that time. I just can't do the thning. My OS is win7. It does the job when it comes to calculate 2+3 or something like that. You get the answer when you press enter. But when it comes to variable eq.s like x+3=2 or 2x+3y=4 when you press enter, nothing happens. ıt just...

There is an animation of a falling rod in simulink here www.youtube.com/watch?v=lJEHzW-sp5c

How would that be presented in MapleSim? 

Also for the double pendulum, model in say if the bottom swing were to hit a wall?  Also model if two double swinging pendulums were to hit each other? 

How can I solve a pair of recurrence relations like this in maple 16?

{A(k)=1+((n-k-2)

Hi

Is there a way of importing data in NetCDF format into Maple 15? This format is very widely used in atmospheric sciences as a data standard for experimental data such as satellite-derived data.

Thanks

I have the following expression  f(t)=0.342 Dirac(t)+6.352 exp(-4t)+.0981 exp(-3.056t)  I want to convert it to a piecewise function of the form given below

 f(t)=0.342  if t=0

 f(t)=6.352 exp(-4t)+.0981 exp(-3.056t)      if t>0

when I applied                     convert(f(t),piecewise,t)

I want to solve the equation f(f(-1))=sqrt(2)+g(f(2)), where

f:=x->a/x^2-3*x+2 and g:=x->a*sin(2*x), a is an unknow. I tried

restart:
f:=x->a/x^2-3*x+2:
g:=x->a*sin(2*x):
solve(f(f(-1))=sqrt(2)+g(f(2)),a):
evalf(%);

and receive 13.02210936+4.135282756*I. 

I just updated to 16.02, and now the (writing) cursor has horrible problems, especially in text groups. Basically, it is erratic or unmoveable.

In a text group, if I move a cursor down by pressing <enter>, it will not move up with the arrow keys, or it disappears and then appears in previous groups. or a new cursor appears in the line above, but the old cursor remains, or ...

In an execution group, it does a lot of the same things, but not quite as erratic.

Prove that .If

This is my code - and I get the wrong output.... shouldnt it be around 900 K something?

restart:with(Units[Standard]):
T:=1200*Unit('degF');convert(T,'units','K');Units[UseSystem]('SI'):
evalf(%);
                    1200 Units:-Unit('degF')
                     2000                 
                     ---- Units:-Unit('K')
                      3                   
                  666.6666667 Units:-Unit('K')
T:=1200*Unit('Fahrenheit');convert(T,'units','K');Units...

 Greetings,

I own Maple 15 Student License and I would like to change the HDD of my laptop. Is this going to pose any problems ? I am going to use the same laptop. 

Thanks 

Hello everybody,

I just realised Maple is allowed for my upcoming exam after New Year.

My plan is to have templates of the most common math problems, I might encounter for quick solutions.

Anyway, I have run into a problem with Laplace shifted data, particularly initial value problems. I have been searching for HOURS, and feel like I have look up everything on google, maplesoft and other sites without succes.

I hope some of you are able to help me. The exercise is:

Hi,

I'm trying to resolve a problem in physics (movement of a particle in a magnetic field) and plot it. I need initial conditions on both (x,y) and (x',y') but when I'm trying to put the four conditions in the initial list of DEplot, a mysterious mistake arises :

Error, (in dsolve/numeric/process_input) invalid specification of initial conditions, got {0 = 0, 0 = 1}

But here is my worksheet :

How to solve Function With Complex Numbers ????? 

please help .....

z^(1+I) + I  = 0

Hello,

I'd like to solve  a system of 3 équations and 3 unknows. The system is composed with 3 trigonometric equations and the unknows are the angles gamma_e[1], psi_e[1],phi_e[1] which belongs between 0 and PI.
I have tried this with SOLVE function and i didn't have any results
