I found that this also works by using the auxiliary equations you showed us before. m(m-1)+bm+c. Are there any cases where this might not work? so far it has worked twice for me!
How do we solve using the formula if there is no P(x). I have a homework problem asking to solve y''+36y=0 by using the formula. I've read in other places that you cant use the formula in this case. I'm pulling my hair ou trying to figure this out.
Sir I am not able to solve this question Q. Solve using reduction of order given that y = e^x ( x + 2 ) \frac { d ^ { 2 } y } { d y } - ( 2 x + 5 ) \frac { d y } { d x } + 2 y = ( x + 1 ) e ^ { 1 } This is a question in my assignment please help me out
NAILA AHMED yes this solves when RHS is zero. However, you can use this solution associated homogenious to solve the particular nonhomogeneous solution.
Great video, thank you so much. Are there exceptions to this short cut? Like some problems this wont work for?
I had a lot of fond memories taking this course, and you certainly helped made these concepts clear for a lifetime.
this solved the whole exercise in less time, thank you

I see, I think it wont work for certain complex root cases.

You saved my life. These videos are so helpful :)
This is very helpful, thank you ❤
can this formula apply for any reduction of order excercise? are there any exceptions that you can not use it?
Shouldn't P(x) be (-3/x) or we just focus on the constant by itself?
Thank you. Very clear and easy to follow.
Sir I am not able to solve this question
Q. Solve using reduction of order given that y = e^x
( x + 2 ) \frac { d ^ { 2 } y } { d y } - ( 2 x + 5 ) \frac { d y } { d x } + 2 y = ( x + 1 ) e ^ { 1 }
This is a question in my assignment please help me out
if there is no y' ...would it be used as 0?
thank you sirrr ,now i already understand this chapter please pray for my exam tomorrow hehe
cikerijunior how did you do in the exam
we can use this method when the L.H.S is equal to 0?
NAILA AHMED yes this solves when RHS is zero. However, you can use this solution associated homogenious to solve the particular nonhomogeneous solution.
can you please PLEASE post a video on Ricatti DE
Thank you Sir!
There's a car honk in the background at 3:36 in case anyone was wondering
How can the integral of 1/x be the ln x? It should be X^-1 and then be X^-2/2
Because the derivative of ln x is 1/x.
Chelsea Beauregard dumbass
Wrong the derivative of x^-2/2 is not x^-1 but -x^-1. also if you integrate with that method you would get x^(-1+1)/0 which would yield undefined.
+hihihihih199 Lmfaoooo
I love you! thanks!!!!
Thanks so much!!!
what if the y1 is not given?

tsegsh
excellent!!!!
Thanx
Thanks man
