The two geometric sum formulas are: The geometric sum formula for finite terms: If r = 1, S n = an and if r≠1,S n =a(1−r n)/1−r; The geometric sum formula for infinite terms: S n =a 1 −r. hallomystictm maskWebJun 15, 2024 · If \(f(t)\) and \(g(t)\) are both odd, then \(f(t) + g(t)\) is odd. Similarly for even functions. On the other hand, if \(f(t)\) is odd and \(g(t)\) even, then we cannot say anything about the sum \(f(t) + g(t)\). In fact, the Fourier series of any function is a sum of an odd (the sine terms) and an even (the cosine terms) function. hallon autumn bliss
