1/2 − 1/4 + 1/8 − 1/16 + ⋯. Demonstration that 1 2 − 1 4 + 1 8 − 1 16 + ⋯ = 1 3. In mathematics, the infinite series 1/2 − 1/4 + 1/8 − 1/16 + ⋯ is a simple example of an alternating series that converges absolutely . It is a geometric series whose first term is 1 2 and whose common ratio is − 1 2, so its sum is.
1/2 + 1/4 + 1/8 + 1/16 + ⋯. First six summands drawn as portions of a square. The geometric series on the real line. In mathematics, the infinite series 1 2 + 1 4 + 1 8 + 1 16 + ··· is an elementary example of a geometric series that converges absolutely. The sum of the series is 1. In summation notation ...
1,3-Propane sultone is the organosulfur compound with the formula (CH 2) 3 SO 3. It is a cyclic sulfonate ester, a class of compounds called sultones . [ 2 ] [ 3 ] It is a readily melting colorless solid.
The idea becomes clearer by considering the general series 1 − 2x + 3x 2 − 4x 3 + 5x 4 − 6x 5 + &c. that arises while expanding the expression 1 ⁄ (1+x) 2, which this series is indeed equal to after we set x = 1.
For example, raltegravir is an HIV drug which contains an 1,3,4-oxadiazole ring. Other pharmaceutical drugs containing the 1,3,4-oxadiazole ring include fenadiazole, zibotentan, and tiodazosin. 1,3,4-Oxadiazole derivatives can be synthesized in a variety of ways. [3] One pathway is from oxidation of tetrazoles in the presence of aldehydes. [4]
