Why are we allowed to differentiate both sides of something like
##y=x^2##
but not something like
##x=x^2##
I believe the answer might be that the first equation is an identity that is true for all values while the second equation is an equation and is only true for some values.
Although I’m not entirely sure if this is correct, and if it is correct, I’m not entirely sure how to distinguish between identities and equations.
