The title says it all, what is the difference between the curly d used for derivatives and a normal d in derivatives. When do you know when to use each one? Thanks

Curly d is used for partial derivatives. Regular d is for a total derivative.

Partial derivatives are when treat one variable as a variable and keep the rest as constants ignoring the relationship between the variables.

Total derivatives are when you do the same as above but the relationship between variables remains.

Thanks, i did remember the curly d being used a lot in partial deriv's, but wasnt sure that was their sole use. Thanks for clearing it up
