Ans: Let the number of balls in three boxes be X, Y and Z. Below, the rounded corner rectangles are representations of boxes.
We see that X + Y + Z = 8 with X, Y, Z >= 1 and <=6. If we put two sticks between 8 balls, is it an equivalent representation of the above scenario?
The order (which stick you put first and which you put second) in which you select those two gaps is not important. And when the order is not important, it gives rise to "Combination". So from the above diagram, there are only 7C2 ways of doing it, that is the number of ways you can put two sticks in any of the seven gaps between the eight balls. You can play around with this experiment by clicking the green button.
As Hyperbolic Function are expressions of "e", first we have to tell what "e" is: The number e, also known as Euler's number, is a mathematical constant approximately equal to 2.71828 which can be characterized in many ways. It is the base of the natural logarithms. It is the limit of (1 + 1/n)^n as n approaches infinity, an expression that arises in the study of compound interest. It can also be calculated as the sum of the infinite series:Tags: Mathematical Foundations for Data Science,What are Hyperbolic Functions?
