Taking differential equations course, this is text:
Ordinary Differential Equations, Zill, 9th edition
is this good?
besides book does anyone have any online resources to help with course (eg khan)??
i think the real name of the book is
First Course In Differential Equations Ed: 9
not sure why they listed it with a different title

>9th edition
>is this good?
No.
You'll find this useful.

>Zill
Haha, no.
It's a shit book.
Vladimir Arnold's Ordinary Differential Equations is a good book if you want something gentle but rigorous.
>>8074016
yes gentle is good, i am not strong in math and long time since taking calculus and algebra
also i havent taken linear algebra yet
>>8073867
what shitty university would use that book for a DE course?
>>8074024
its differential equations for life sciences

My community college used the 10th edition of Zill.
It's just a cook book for solving odes. The 'theory' behind it is really simplistic. The section on variation of parameters is pretty good. I forgot the algorithm on an exam, but remembered that variation of parameters is basically just Cramer's rule with the general solution of differential equation and I was able to derive the algorithm on the spot.
The tenth edition is pretty good for application problems. So, if you are an engineer, or a physicist you are golden. Good for an intro to diff eqs.

Highly recommended.

You'll need this for ODEs for sure.
>>8073867
Use Simmons' ODEs book.
Best lectures I found when I took diff eqns: Math 391 - Methods of Differential Equations - Spring 2015: http://www.youtube.com/playlist?list=PLYoxM3oLTvxJG4eG_cB6RAol_93YkxcJB

>Math 391 - Methods of Differential Equations
It's a 3rd year module? What does it contain briefly?
>>8074173
1st and second/higher order ODEs. I took a class with the same text as OP and the lectures synced pretty well to the class.
>>8074196
Looking through it is seems like a second year module at best...
>>8074204
What year it is or isn't doesn't matter. If op wants lectures on the subject of ODEs, they're good ones that are taught well.
