Nettet21. nov. 2016 · Let u(x) = 1 + x2 then du(x) = 2xdx. d(u(x)) 2 = xdx. Start solving the integral. ∫ x x2 +1 dx. = ∫ d(u(x)) 2u(x) = 1 2 ∫ du(x) u(x) = 1 2 ln u(x) +C. = 1 2 ln∣∣x2 +1∣∣ +C. Because x2 +1 > 0 then ∣∣x2 + 1∣∣ = x2 + 1. NettetThe integral sign ∫ represents integration. The symbol dx, called the differential of the variable x, indicates that the variable of integration is x. According to the standard ISO 80000-2:2024, the differential symbol should be printed in Roman (upright) style as it is an operator and not a variable. halfway home rescue inc. north haven ct
