good evening sir. At 1:20, why did not you use partial derivative instead of the complete derivative. what is the logic in using "d" instead of "dell"?

[@adityagupta_1995]

Can't we stop with the expression where MR is expressed in elasticity form without taking absolute value of elasticity & without changing sign from '+' to '-'?

[@nishantmehraecopoint]

Yes you can. But then you have to think in terms of e < > = -1

@@nishantmehraecopoint got it. Thank you for clarifying 🌼
