Hi Jesse, with Distribute[Integrate[a + z + s[z], {z, clow, chigh}]] you get: chigh^2/2 + a*(chigh - clow) - clow^2/2 + Integrate[s[z], {z, clow, chigh}] Peter Am Mon, 31 May 2010 03:45:33 +0000 (UTC) schrieb Jesse Perla <jesseperla at gmail.com>: > I have an integral involving constants and an 'unknown' function.
