Hello out there,

i just started using maple for some kinetik calculations.

it is a combination of the following formulas:

 

Lo := piecewise(sin(t) < 0, 0, sin(t) >= 0, sin(t))

L := Lo*(int(2*exp(-b*x(t)*(j*cos(phi)+sqrt(J^2-j^2*sin(phi)^2))), phi = 0 .. Pi))/Pi

r:= (int(u*L*j/(L+k), j = 0 .. J))/J^2

diff(x(t), t) = -B*x(t)+x(t)*r

 

The values would be:

 

b:=1
u:=1.2
J:=2.5
k:=3
B:=0.8

 

 

I want to plot x over t and get the values for it...
I tried several aproaches, but nothing realy worked...
Thanks a lot
