In Calculus, one usually finds the fist derivative of a function, and then find the second derivative of the function by finding the derivative of the first derivative.

I am wondering if it is possible to bypass finding the first derivative and go straight to the second derivative. Is there a formula for this?

Many thanks!

You have to take limit of limit
or
do first one in mind and write second one.
I THINK YOU CANNOT DO IT

No. The second derivative is the first derivative of the " first derivative. Sorry

y = Ax
You don't have to know what A is to know that d²y/dx² = 0

Typically you do need to find the first derviative to find the second derviative. You can thought find the 50th dervitiave of an equation without having to take 49th dervtiave by taking like 10 derviative and seeing if there is a pattern.
