Re: system of linear differential equations

I have a problem solving the following system using LDEC command

(1)
dx1/dt = ax1+ bx2 +k1
dx2/dt = cx1+fx2 + k2
a,b,c,f = constants

in the manual the system shown has the form
(2)
ax1'(t)+bx2'(t) = 0
cx1'(t)+fx2'(t) = 0
a,b.c,f = constants
x1' , x2' first derivative of x1, x2 variables
is there a way to solve (1) with other command?

You just have to read the manuals

Your function is typically Y(X)
first derivative of the 1st variable is d1Y(X)
double derivative is d1d1Y(X)

in case you have two variables Z(X,Y)
then d2Z(X,Y) would be derivative according to second variable Y

more in the manuals
AND
your calc has a HELP system for all the new CAS commands
unfortunately not for the old
