It’s been about 3 years since I took a class in ODE’s. Variation of parameters was one of those techniques i forgot how to use, so this a great refresher. And I’m surprised to hear that someone used this technique in PDE’s, I got stuck using the method of undetermined coefficients a lot.
Wow, Sir! I suddenly miss the physical lectures and university life while watching your videos. I hope that this pandemic ends soon so that we could go back to the normal setting where the fun, exciting, and interactive lectures happen. You're a cool professor. I wish I could be in one of your classes. Greeting from the Philippines!
Same here Gabe! Just started my D.E. class at RCBC and figured I'd get a head start and found these awesome lectures, I definitely wish I were back in the classroom and even more so learning D.E.'s from the Math Sorcerer haha
Hey! does it matter what we select as our y1 and y2 when we go to compute w, w1 and w2? i notice it changes the signs if you change your y1 and y2, but does this correct itself working through the problem?? Thanks!
I really got discombobulated while doing higher order DE with this method so can you please make a video on that please it's a request as only yu can clear all the doubts .
If I had to take an educated guess after watching this, higher orders would have a W with the number of orders rows & columns (so a 4th-order ODE would have a 4x4 W), and you would have W_1 to W_maxOrderNumber with each W_# having the respective column 'blocked out'), then you would have to take those determinants which can be a lot of arithmetic, then eventually the multiple integrals in the next step.

this looks like the most fun math class to be in! love the lectures

Sir your lecture is very nice iam Pakistani when I watch your lecture I become able to full exercise of book
Awesome👍

It corrects itself so it doesn't matter, good question
Awesome! Thanks! @@TheMathSorcerer
Awesome lecture. Very useful technique.
thank you!
Great video, thank you!
Professor , is there a Lecture 5? it's not there in the playlist so I am curious. Btw Love your lectures!!
Chapter 5 of the Zill textbook only goes over applications.
I'm guessing it wasn't covered in this class.
God among men
Thanks!
It’s a sinch!!!
Yes hahaha
