## How do i switch between time and angle?...

Hey there,

i have an System in the form below.

I try to plot s over the angle t which is used in the functions (S,DS and DDS) but because maple uses t in the functions (s, v and a) as the time the calculated eigenfrequency doesnt fit to the System.

The eigenfrequency should be omega:=sqrt(c[0]/m[1])=1035 (over 360 degrees) but because of the angle time switch the eigefrequency is 1035 (over 1).

Has someone an idea how i can tell maple that t is an angle in degree? ...

## How do i supress the output?...

Hey there i have written the following code and it gets very slow cause of the output at each step, which is not needed. I only need the arrays at the end of the procedure. Has someone an idea how i can suppress the output for the steps betweend the start and the end of the procedure?

restart:
s_1 := 0.779e-1*t^2-.1345*t+.2031:
s_2 := 1.3502*t-6.8742:
s_3 := .1112*t^2-1.5108*t+11.527:
s_4 := 1.9322*t-15.099:
s_5 := -0.178e-1*t^2+2.648*t-22.312:

## How can i follow the work of an procedur...

Hey there,

if sometimes problems with my procedures, so i´m looking for a command which shows me the what the procedure is doing.

The command i´m looking for makes a green output :P. Sadly i forget the command; maybe someone can help me.

Best regards

## How do i plot in an procedure ?...

Maple

Hi,

i have to make an iteration in the following way, but i have a problem to plot the result. Has someone an idea how to plot?

s_1 := 0.779e-1*t^2-.1345*t+.2031:
s_2 := 1.3502*t-6.8742:
s_3 := .1112*t^2-1.5108*t+11.527:
s_4 := 1.9322*t-15.099:
s_5 := -0.178e-1*t^2+2.648*t-22.312:
V_0 := .3*.15:
p_0 := 100000:

t:= 0:
tmp:= p_0:
S := 0:

while t do

if t >= 0 and t if t > 9.5 and t if t > 12.875...

## How do i solve an ODE in degree?...

Hey there,

how can i solve the following ODE in degree and not in radiant... numerical solution is required... im allways getting the wrong eigenfrequency.

>m*D(D(x))(t)+d*D(x)(t)+k*x(t)=sin(2*t)
