The partial sums of the series 1 + 2 + 3 + 4 + 5 + 6 + ⋯ are 1, 3, 6, 10, 15, etc.The nth partial sum is given by a simple formula: = = (+). This equation was known ...
1,1,6-Trimethyl-1,2-dihydronaphthalene. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 1,1,6-Trimethyl-1,2-dihydronaphthalene ( TDN) is an aroma compound present in wine, [1] particularly aged Rieslings. [2] [3] Chemically, it is classified as a 13C-norisoprenoid, as it has ...

The metallic green and brown insects are known to feed on more than 300 species of plants, including roses, ornamental trees and vegetables.
Adding 4 hours to 9 o'clock gives 1 o'clock, since 13 is congruent to 1 modulo 12. In mathematics, modular arithmetic is a system of arithmetic for integers, where numbers "wrap around" when reaching a certain value, called the modulus. The modern approach to modular arithmetic was developed by Carl Friedrich Gauss in his book Disquisitiones ...
Zone 5 uses eight 2-digit codes (51–58) and two sets of 3-digit codes (50x, 59x) to serve South and Central America. Zone 6 uses seven 2-digit codes (60–66) and three sets of 3-digit codes (67x–69x) to serve Southeast Asia and Oceania. Zone 7 uses an integrated numbering plan; two digits (7x) determine the area served: Russia or Kazakhstan.

In mathematics, an alternating series is an infinite series of the form or with an > 0 for all n. The signs of the general terms alternate between positive and negative. Like any series, an alternating series converges if and only if the associated sequence of partial sums converges .
