Many years ago while taking my beloved calculus class, our class chanced on this problem that none of us were able to get the answer. However, as many math books are, the answer was in the back of the book. Now as any person worth their salt in mathematics would know and understand, that the answer is least important. It is the method by which you were able to solve the problem is paramount.
The following problem took me over 20 years to answer!!!!!!!!! Let's see if you are smarter.
The amount of apples in a basket doubles every minute. It takes an hour for the basket to be full of apples.
Problem 1: At what time would the basket be half full?
Problem 2: Write the expression that resolves problem. (This is the one that took me 20 years to get)
