Homework Statement
Hi, I am just stuck in why / how we can write minkowski metric where I would usually write delta.
I see that the product rule is used in the first term to cancel the terms in the second term since partials commute for a scalar and so we are left with the d rivative acting on a x terms.
I would usually write ##\frac{\partial x^v}{\partial x ^y} = \delta ^{(4)v} _y ##
How is this equivalent to the minkowski metric ?
