just go this video recommended, and you're an extremely good teach, why? because I've never learned differential equations, and it still made snese. You explain these topics in such a good way, that even me, someone who has no clue in this subject can follow along and understand everystep. You state theorms so well and clear that I went like 'obviously, you reduce it to an auxilary form' when I've never heard that before. Kudos, and keep up the good work man!

at 2:30 you make lambda less than 0, but then define the characteristic polynomial as r^2 + lambda = 0. Wouldn't it be r^2 - lambda = 0?
@oliveraherne5547
@oliveraherne5547 5 жыл бұрын
No, he's substituting lambda in, not minus lambda. He's saying lambda is a minus, not that lambda is being multiplied by a minus.

At 5:10: I don't understand what you meant when you said "Both these terms are not equal to zero but I have things multiplied that are equal to zero." Which ultimately results in C1 equaling to zero. Can you clarify this part? I'm still confused.

@fancybluepen3489
@fancybluepen3489 5 жыл бұрын
Well that really depends on what you want the independent variable to be. Whether you use t or x is pretty arbitrary from a pure mathematical standpoint cause they are just symbols we attach to help us describe y being changed with respect to this variable at the end of the day. It doesn't really matter as long as you stay consistent with your math. It only really matters if you are talking from a physics standpoint and usually you would use t cause most of the time, time is your independent variable.
