Is it possible to perform a Ztransform with initial conditions in Maple?
I want to calculate the Ztransfrom of following differrence equation.
y(-1) = 1
y(-2) = 2
For now I am using following command.
I suppose that this command uses initial conditions zero.
Thank you in advance,
I convert following differential equation to the s domain:
As solution I get:
s^2*laplace(y(t),t,s)-D(y)(0)-s*y(0)+3*s*laplace(y(t),t,s)-3*y(0)+2*laplace(y(t),t,s) = -30/(s+3)
It's not really a Maple problem but I don't understand why the right hand side of the equation is -30/(s+3) .
When I transform the right hand side of the differential equation manual to the laplace domain I would do it as:
diff(x(t),t) = s*X(s) = s * 10 /(s+3)
Is there a way to solve following equation in maple? I have already tryied intsolve and dsolve without succes.
I have been trying to solve the following differential equation with 2 starting conditions.
(It's the equation of a mechanical vibration).
>diff(x(t), t, t)+4*Pi^2*x(t) = 200*sin(hoekvers*t)
>Opl:=x(t) = -100*sin(2*Pi*t)*hoekvers/(Pi*(4*Pi^2-hoekvers^2))+5*cos(2*Pi*t)+200*sin(hoekvers*t)/(4*Pi^2-hoekvers^2)
Now I want to plot the graphic of this vibration when hoekvers=2*Pi.
(In that case there is resonance)
I get the error dived by zero. As you see the numer is zero when I fill in 2*Pi.
For 2*Pi+0.000000000001 I get no error and a good graphic but this is not a good and exact method according to me.
I am using Maple since a year and I am used to work in the classic worksheet.
Now I wanted to try out the regular worksheet (you also have document mode). This worksheet is completly different from the classic one. By example I can not find a way to insert text in that worksheet. I click 'text' (F5) then 'Maple Input' is highlighted. I change it to 'text' and type some text. I press enter and ' ";" is missing ' is displayed. This is just text not a Maple command... How can I let this sheet now I only want to insert text?
Thanks in advance,
