Homework Statement
(2n-1)!/(2n+1)!
Homework Equations
The Attempt at a Solution
...2n-2*2n-1
------------ (pretend that's a divider)
...2n-2*2n-1*2n*2n+1
Is the answer 1/[2n*2n+1]?
A factorial is a mathematical operation that multiplies a number by all of the positive integers smaller than it, resulting in a large number represented by an exclamation mark (!) after the original number.
Simplifying a factorial can make it easier to use in calculations and to understand its value. It also helps to reduce the number of terms in an expression.
To simplify a factorial, you can use the basic factorial rule: n! = n * (n-1) * (n-2) * ... * 2 * 1. You can also use algebraic rules to simplify factorials in equations and expressions.
One common mistake when simplifying a factorial is forgetting to include all the smaller positive integers in the multiplication. Another mistake is not properly applying the factorial rule or algebraic rules.
Not every factorial can be simplified. Some factorials, such as prime factorials, cannot be simplified any further. However, they can still be written in their factorial form using the exclamation mark notation.
