Calculus Level pending

In case you are just waking up or you just got on brilliant, here is a great problem to warm up your mind with. Also, I'm starting a new set of problems called "the warm ups problem sets." Made of Relatively easy or medium difficulty problems. I will be posting probably 1 or more per day.
