Topics in p r e c a l c u l u s table of contents | home 23 factorials by the symbol n! ("n factorial") we mean the product of consecutive numbers 1 through n. N! = 1· 2· 3· · · (n − 2)(n − 1)n = n(n − 1)(n − 2)· · · 3· 2· 1 the order of the factors does not matter, whether backwards or forwards. 0! Is defined as 1. 0! = 1 (the usefulness of this definition will become clear as we continue. ) example. 6! = 1· 2· 3· 4· 5· 6 = 720 a convenient way to calculate this is to wait to multiply 2· 5 = 10. then 3· 4· 6 = 12· 6 = 72 -- times 10 is 720. Calculations with factorials are based on this fact: any factorial less than n! Is a factor of n!. Example 1. 6! Is a factor of 10!. for, 10! = 1· 2· 3· 4· 5· 6 · 7· 8· 9· 10 = 6! · 7· 8· 9· 10 example 2. evaluate 8!

Is a factor of 8! how long to take viagra before , so it will cancel leaving 7· 8 in the numerator. viagra side effects urdu we will have 7· 8 1· 2 = 28. Problem 1.

viagra cost what factorial is each of these? (consider what each symbol means. ) to see the answer, pass your mouse over the colored area. To cover the answer again, click "refresh" ("reload"). A) 3! · 4 = 4! for, 3!

cheap generic viagra evaluate 10! 7! 10! 7! = 7! · 8· 9· 10 7! = 8· 9· 10 = 720 problem 3. evaluate 12! 10! 2! can you take more than 20 mg viagra 12!

buy viagra cheap 10! 2! = 10! · 11· 12 10! 2! = 11· 12 1· 2 = 11· 6 = 66 example 4. show: 1 (n − 1)! = n n! Solution. if we multiply both terms on the left by n, then 1 (n − 1)! = n (n − 1)! N now, (n − 1)! Is the product up to the number just before n. therefore, (n − 1)! Times n itself is n!. 1 (n − 1)! = n (n − 1)! N = n n! Example 5. show: n! K + n! (n − k + 1) = (n + 1)! solution. on the left-hand side, n! viagra cost per pill 2012 Is a common factor: n! K + n! ( n − k + 1) = n! ( k + n − k + 1) = n! ice cream made viagra (n + 1), on canceling the k 's, = (n + 1)! For, (n + 1) is the number after n. Problem 4. write out the steps that show how to transform the left-hand side into the right-hand side. again, consider what each symbol means. a) 1 3! can you take more than 20 mg viagra = 4 4!
