Thorn Television Rentals Limitedrect to 10 decimal places, then it is usually not worth using a computer. As a more realistic problem consider a series containing a variable y. Let.S is an infinite sum, but as the time available for the calculation is finite, we add only a limited number of terms, say 4, as a first approximation.笨拙的你 发表于 2025-3-27 01:33:32
