i cant quite remember how to do these,
Use the limit definition of derivative to calculate f'(x) where f (x) = 1/
x^3
i want to make sure i understand all the practice examples thoroughly for my exam. i have some previous questions i still need help with, so help on those or this is greatly appreciated!
thats what i initially thought of doing.. is there anything else the question could mean becuase ive only heard that referred to as "the formal definition of the derivitave" i believe
i certainly hope its the way you showed , because i understand that, but do you think its possible that the ? refers to another method?
