Variation of Parameters - Example 1

[@Cobras7111]

You explained neatly in 9 minutes what my professor couldn't in two lectures. God bless ya

[@davemartin157]

A worked example, such as this, is more clear than all the jargon in my text book and worth more than the thumbs up! Thank you!

[@halilhelvaci]

My friend, you just saved my life. Thank you soooo much

[@ennb8695]

We didn't learn the Cramer's rule in our class and the textbook, knowing how to find W1 and W2 saved me a LOT of time, thank you!

[@enriquerce]

This was definitely a lot better than our professor's method. Thanks a lot!

[@HoustonMathPrep]

You're welcome!

[@johnmelaku5247]

you are helpful!!

[@taimoorabbas8662]

You are best math teacher you cleared my all concept

[@kaidokun2742]

Thank you. This seemed so much complicated in class. But this made everything so simple.

[@nurbanudavaz4641]

You have officially become my go-to for math help. Much thanks!

[@hitandrun301]

You made this seem so easy thank you

[@danielponce89]

Fantastically demonstration. I like y'alls software that you minimize and reposition previous work to the upper left. I think your videos are getting me through Diff Equ. :-D

[@indraneelhazra6923]

you saved my 10 marks for this semester hats off to you bro

[@grahamdolsen8507]

U2 is a rock and roll band quite popular in the late 80's in case anybody was wondering

[@GregSalazar94]

Much simpler than the algebraic method. Thanks for the video!

[@laxplyr1982]

+Greg Salazar Agreed, the algebraic method has too much going on and gets confusing. This is really straightforward.

[@phillip6215]

woow glad my classmate found this!!! It's much much more easier than what my instructor would teach!

[@matrixate]

I like how you showed how you get the u' by taking the determinant after column replacement.

[@Gantics-Antics]

Thank you Sheldon!

[@chillbro6142]

Thank you for this!! I was dealing with a problem where an answer was missing a term that I had on my paper. I think I finally realized that the term was combined with one of the terms with an unknown coefficient. You did the same thing with the two terms at the end. I couldn't figure out what I was doing wrong lol

Amazing Math ability

[@ilyosgiyasov3190]

thanks for uploading, much better than my teacher. Is it possible for you to upload video "reduction of order", it's really complicated topic for me

[@CB-td4ck]

dear lord thank you for this video

[@assasinon1209]

much love dawg, papa bless.

[@AegixDrakan]

Freakin' finally something that explains this in a nice concise way. Every other tutorial and my class notes were a mess. x_x Although I wish this vid showed the rules how to actually get the Yc at the start. It took half an hour to find someplace that actually showed the rules for it. @_@ well, at least now I know. Hopefully this will help me on the upcoming test so I can be done with this math course I don't actually need so I can finish this compsci degree and be free at long last. ;_;
