Thank you very much Bignose! That was really killing me.

Hello SFN, I am an occasional lurker who has a question. Well, more or less an inconsistency. This problem was something along the lines of : Find the anti-derivative of (2x + 1)^3. and the inital value if g(1) = 100 The anti-derivative should be : ((2x + 1)^4) / 8 + c And c would come out to be 89.875. I assume we could expand (2x+1)^3 to 8x^3 + 12x^2 + 6x + 1 and proceed to find the anti-derivative, 2x^4 + 4x^3 + 3x^2 + x + c. If we use g(1) = 100, you come up with c = 90. My question is : where is the 1/8 difference coming from? Thanks for your help, RandallJ
