ya this does not seem like a good explanation

bright hull
shy burrow
#

you might want to look at other sources

bright hull
#

any good ones you got?

shy burrow
#

but the super vague idea is making a guess so that you can reduce it to product rule of derivative

Integrating factor

In mathematics, an integrating factor is a function that is chosen to facilitate the solving of a given equation involving differentials. It is commonly used to solve non-exact ordinary differential equations, but is also used within multivariable calculus when multiplying through by an integrating factor allows an inexact differential to be mad...

#

you can maybe start here

bright hull
#

the prime notation they use kinda not obvious to understand too
better if they would have chosen the leibniz

bright hull
shy burrow
#

ya sometimes that helps

bright hull
#

any good counter ones?
which deal easily

shy burrow
#

but regarding notation of derivative you should be comfortable with either

#

hm

#

i think boyce and prima is alright for proofs

#

the over all content is all over the place imo tho

bright hull
#

i am a first time learner

#

for ode

shy burrow
#

ya boyce and prima should be fine

bright hull
#

oh alr i will check it out

bright hull
#

the prime one

#

is idk

#

very uncomfortable

shy burrow
#

fair, but I think its good to get comfortable with both imo

#

but in the end its just notation

bright hull
#

do you think

#

it should take for odes to complete

shy burrow
#

fully depends on how much time you commit to it

#

you can finish ode in a week if you want

#

finish meaning go thorugh the book and do every problem

bright hull
#

one last question

#

do you know the book "calculus made easy" by thompson?

shy burrow
#

no

#

have you done calculus?

bright hull
#

oh...

#

yes.

shy burrow
#

or at least multi calculus?

bright hull
#

yes

#

done

shy burrow
#

ah ok

#

then ode should be fine

bright hull
#

yea i bet

#

i was wondering if i could get a small book

#

with an easy to go content

#

questions i can get from anywhere

bright hull
shy burrow
#

?

#

for calculus or ode

bright hull
#

ode

shy burrow
#

hm

#

not sure about it

#

i mean ig you can check mit ode lecture vids

bright hull
#

i tried to watch one but it wasnt that good, so i switched to lectures

#

and yt got few only

#

on odes

Let me introduce you to the holy grail of undergraduate math guides:

https://tutorial.math.lamar.edu/Classes/DE/DE.aspx

Differential Equations

Here is a set of notes used by Paul Dawkins to teach his Differential Equations course at Lamar University. Included are most of the standard topics in 1st and 2nd order differential equations, Laplace transforms, systems of differential eqauations, series solutions as well as a brief introduction to boundary value problems, Fourier series and ...

I find pauls notes to lack theory maybe I havn't looked into it as much

#

i think if you're doing pure math really finding the right textbook is the best thing to do imo

#

do ya got any?

#

i understood the equation ch so well

#

tysm

for this

loved this book

# bright hull yes

There's 3blue1brown's excellent video series about linear algebra on YouTube, but I suppose that's not what you want.

bright hull
#

i dont need that

#

i alr watched them
