Session 10: Steady two dimensional heat equation: Proof, an example and hints for different types

[@aryabhatt7375]

0:52 it is wave equation

[@DrMathaholic]

Thank you. Dear Viewers, at 0:52, the term on the left hand side of the equation is of first order and not second order derivative. For heat equation: first order For wave equation: second order.

sir at 20:06 we should directly put A*n in the equation of u(x,y), don't need to calculate An because we will directly get the value of A* itself Also at start you wrote d2u/dt2 but I think it should be du/dt though it doesn't affect the derivation

Thank you Sir for all the top class content which you are providing to us. As a COEP student, I know the value of your lectures. Thanks a lot sir ☺️

thank you sir 🙏 now my concept is clear it was the best lecture over all channeles

Sir, at 18:47, the property is for integration from -a to a but, our integration was from 0 to 2. Then how it is applied to this integration?

[@DrMathaholic]

Good question!! I was expecting someone to ask.😀

[@DrMathaholic]

Integrand is even function so I write outside 2/2 then numerator 2 will go away when I write limits -2 to 2. Then i can apply this theorem.

[@DrMathaholic]

I hope this clears your doubt.

Pls elaborate how we will change x & y in this general equation if the boundary conditions is 1 on right, bottom and left wall
