how do i choose appropate values for t if i have other ODEs to plot?

 

how do i choose appropate values for t if i have other ODEs to plot?

 

may i ask why i have to use systems of ODEs here?

 

 

this is helpful

 

thanks

ooops

 

yes

 

it's something like arctan (AAAAAAAAA, BBBBBB)

 

horrible exoression

for dx/dt=x/t

i know that we can use this method to draw "normal "isoclines

by rearranging it and set x/t = constant

so isocline for that are straight lines

i just dont get it, why maple response would give me curly curve...

 

cheers

yep thanks "map" is always very handy though i didnt use it very often. I will try to use that more often ============= For Maple on MAC how do i open classical worksheet if it is not on the desktop?

i see so basically if i just ask it to solve with initial condition given i wont know if the solution is unique or not thanks

i know i can do that this way

 

however

 

if i draw it by hand

 

i rearrange that to x/t=c ( c is constant)

then x=ct are they suppose to be straight lines??
