 Author Comment/Response Claudio ORyan 06/07/12 11:14am Hi. I would like to integrate the formula below. Mathematica does not give me a results for the second integrate, only for the first. Some idea? R2 = 4*2.54/100 (*metros*) R1 = 2*2.54/100 Mu0 = 4*Pi*10^(-7) Br = 1.5 M = 4*Pi*Br*Mu0 Nm = 32 n = 0 j = 1 g = 2.5/10/100 T = 1/4*2.54/100 H = 0.8/10/100 z1 = 0 z2 = T zeta[j_] = If[j == 1, z1, z2] Bfi[r_, fi_, z_] := Integrate[(z - zeta[j])*Cos[fi - fiprima ] * rprima /((r^2 + rprima^2 + (z - zeta[j])^2 - 2*r*rprima*Cos[fi - fiprima])^0.5)^3, {fiprima, \ (4*n + 1)*Pi/Nm, (4*n + 3)*Pi/Nm} , Assumptions -> R1 <= r <= R2 && R1 <= rprima <= R2 && (4*n + 1)*Pi/Nm <= fiprima <= (4*n + 3)*Pi/Nm]           Bfiavgtop1[r_] = Bfi[r, Pi/2, -g] Bfiavgtop2[r_] = Integrate[Bfiavgtop1[r], {rprima, R1, R2}, Assumptions -> R1 <= r <= R2 ] regards Claudio URL: ,
