Web23 Mar 2024 · The sum of the harmonic sequence formula is the reciprocal of the sum of an arithmetic sequence. Thus, the formula of AP summation is S n = n/2 [2a + (n − 1) × d] Substitute the known values in the above formula. S n = 5/2 [2x12 + (5-1) X 12] = 180. Hence, the sum of 5 terms of H.P is reciprocal of A.P is 1/180 . WebChoosing harmonic gauge implied the four conditions (6.35), which brought the number of independent components down to six. Using our remaining gauge freedom led to the one condition (6.40) and the four conditions (6.41); but when = 0 (6.41) implies (6.35), so we have a total of four additional constraints, which brings us to two independent components.
