You must use square brackets for functions. Note what happens in what you entered if the xx is replaced by bb. bb Cos (aa bb) aa*bb^2*Cos Integrate[xx Cos [aa xx], xx] Cos[aa*xx]/aa^2 + (xx*Sin[aa*xx])/aa Bob Hanlon In a message dated 2001/5/4 12:34:13 AM, berkson at home.com writes: >The Mathematica solution to the indefinite integral below doesn't agree >with >that found in my CRC tables. > >Integrate[xx Cos (aa xx), xx] >= (1/3) aa Cos xx^3 > >The CRC table gives: (1/aa^2) Cos (aa xx) + (xx/aa) Sin (aa xx) > >The Mathematica solution doesn't look right.
