Best ResponseYou've already chosen the best response.0Possible intermediate steps: integral x sin(x) dx For the integrand x sin(x), integrate by parts, integral f dg = f g integral g df, where f = x, dg = sin(x) dx, df = dx, g = cos(x): = integral cos(x) dxx cos(x) The integral of cos(x) is sin(x): = sin(x)x cos(x)+constant
