Reply 4# jie_kumiko

jwpn no. 4(b) salah

equation 1& 2 are heavily dependent

klu: gugel Eigenvalue solution for Differential Equations

dausss....!!!
yg no 4a tu kan...
kalo nk integrate....utk factor v(x) just amik yg dy/dx je ke??
yg 2nd order aku xblajo lagik ler...
cer bg hint

dauswq · Post time 2-5-2010 10:55 AM

y dan x are depend on t.....

so we need to solve both equations together

jie tak belaja lagi ker
tak pe..amik soklan ni sbg warm up

cara penyelesaian: check Euler solution for DE..yes it is indeed 2nd order, but not homogeneous equations

tp xdan nk redo ......
nk mkn nasik dagang da nie...

dauswq · Post time 6-5-2010 11:46 AM

up up up
tak de org jwb ker?
aritu kemain request:cf:
