i think there is a mistake in c1^2 term at 7:23..it should be 1/3..
plzz correct me if i am wrong

[@TheMathVirtuoso]

yes, you are right. Thank you for writing here. Will correct it in the annotation. 🙂

[@mathematicsandabstractions]

Thank You

[@anujbhagat4188]

Can I get a reason why did we consider the approx. solution as c_0 +c_1x+c_2x^2? why didn't we take the solution of degree 3 or 4?

[@rashminphadte1117]

Amazing initiative Ma'am🙏🙏♥️♥️

Investigating the vibrations of a fixed wedge of constant thickness.we have to examine the extremal of the functional
v=integral 0 to 1 ( ax^3y''^2-bxy^2)dx
y(1)=y'(1)=0
Where a and b are positive constants
Mam i want solution for this problem
Please try to upload mam

[@gomathik6276]

Plz solve this mam upload video mam

[@TheMathVirtuoso]

Gomathi, will try to make it for sure.

[@gauravsingh632]

How much is left in this chapter

[@TheMathVirtuoso]

Gaurav, sorry for the late reply. There are few more topics from the chapter is there.

[@antonyshiltonka908]

go ahead ..... shortly your channel will have reached to more students.(EPIC guarantee)

[@TheMathVirtuoso]

Thank you very much 👍

[@shloksaxena8331]

I guess your answer is not right ...
