This was helpful. Thank you for your time sir.
Hello sir, the example on page 54 of the class note isn’t clear. I don’t understand why delta ki,kj and 3 are d ones outside the matrix.Regards.
Rukayat, go ahead and carry out the determinant expansion by yourself and tell what you will have. All you then need to observe is that when the indices of the Kronecker delta are the same unknown indices, the value becomes 3 as shown in example 12.
Got it! Thank you sir
nice, that was also helpful. the comma also got me confused.
