In there, we have two numbers: a a and n n. When we look at the symbolic picture in there, we see that n n is the order of the root, so we input n = 18 n = 18. In turn, a a is the number under the radical, so we take a = 1.5597 a = 1.5597. This makes the root calculator spit out the answer to be: WebThe sum of the first n triangular numbers is the n th tetrahedral (triangular pyramidal) number, P (n). T (1) + T (2) + ... + T (n) = P (n), and P (n) = n (n+1) (n+2)/6. 4. The infinite sum of the reciprocals of the triangular numbers is 2. This can be demonstrated as follows: Σ n=1...∞ 1/T (n) = Σ n=1...∞ 2/ [n (n+1)] = 2Σ n=1...∞ [1/n - 1/ (n+1)] oysho shop online nl
