dexterciby: This is works perfect.
however, it certainly interfere with my previous knowledge about non homogeneous EQ's. one of the solutions for the characteristic equation is e^(-5t), wouldn't we have to multiply everything by another "t"?
Please explain?
This problem is hindering my overall work !
Need to find particular solution.
y"+6y'+5y=-9te^(5t)
What would be my guess work: I tried y_p=Ate^(5t)+Bte^(5t)
Any thought on the guess?
Thanks,

OH man how could I have missed that,
thanks GrowlEdit: To make Crowl, oops..., Growl happy, I am changing the last word of my original post from Crowl to Growl.
Sorry Growl,
Oh guy's: what is the function with the initial condition involve values at two points? Like y"-12y'+32y=0; y(0)=6 and...
Ok, so i tried to solve this problem:
Find y as a function of t if:
100Y"-729y=0; y(0)=6, y'(0)=1
this is what i did so far:
100r^2-729r=0
r(100r-729)=0
r=0, r=729/100
y(x)=C1+C2*e^((729/100)*t)
y'(x)=C1+729/100C2*e^((729/100)t)
am I on the correct track? After I substitute the...
