You just helped me so much on my ODEs test. I wish my professor taught the way you did! Great job.

@1:30 How did you know it was going to be: *yp = Ae^tsin(t) + Be^tcos(t)* ? A bit more explanation is needed there.
What happens if the equation is y'' - 3y' + 2y = 3t ?
What happens if the equation is y'' - 3y' + 2y = tan(t) ?
How does that piece change? Thanks.

Ive been looking for examples of
X^n*sin(x)
Or X^n*cos(x)
But haven't seen any on youtube. Any one know some links? Thanks.
