The factorial of the number 0 is defined as 1 because there is only one possible permutation for a set of zero elements, namely the empty set. The combinatorial interpretation of the factorial function is the total number of possible permutations of a set of n elements.
Continue ReadingA permutation can also be defined, in this case, as a way of arranging the objects in question. The factorial function "n!" of a positive integer n is defined as the product of all the positive integers smaller than or equal to n. It can be recursively defined as "n! = n × (n ? 1)!," where 0! and 1! are known to have the value of 1.

When analyzing certain substances, scientists are often unable to get a completely accurate understanding of the substance's makeup. With a calibration curve, chemists can compare known information about unknown substances to make estimates about its makeup and chemical properties
Full Answer >A sine bar is a hardened steel bar set on two cylinders whose centers are an exact distance apart. They are used by machinists in setting materials at precise angles during milling, grinding and inspection.
Full Answer >Two sets are said to be equivalent if they have the same number of elements in each set. Two equivalent sets are represented symbolically as A~B. Equal sets are always equivalent, but two equivalent sets are not always equal.
Full Answer >When you cube a number, you multiply it by itself three times. A cube root is the value that, when cubed, gives you the original number. One way to find the cube root of a value is by going down the numbers and cubing them until getting the original value.
