Hello everyone,
The derivative of function
is
, what i understood is if function
represents the graph of time and displacement, its derivative at a point on graph tells me the instantaneous velocity.
Question 1: since we find derivative by making the
as small as we can lim->0 but we never make it a point, so why do we call it derivative at a point ? or instantaneous velocity at a point. it better be called velocity as x approaches at that particular point.
If
represents the area of square its derivative
represents change in area when side is changed by small amount. but when i put in numbers in
it just tells me the area at that particular point.
Question 2: if it tells me the area of square at particular point where is the notion of change coming in ?
and it is not accurate as it ignores the
part, i could have found out the area of square much more accurately by simply putting the value in the function.
