dear mathgroup members i have juz started using mathematica not too long ago and i was trying to solve the following 3 integrals, but it seems that i wasnt able to do it using mathematica as it always return the original expression. Even trying to simplify the expression on the right hand side was to no avail. can anybody help me?? thanks in advance. 1) b = Integrate [Integrate [[Exp[-5(Ln(z))^2-0.5(w)(z)]][(w)(z)]^9], {z, 0, infinity}], {w, 0, a}] b is known and trying to solve for a where both w and z are independent variables. ***************************** 2) b = Integrate [Integrate [[[[(w)(z)^(3/2)]^(-1)]Exp[-5(Log(w)(z))^2-(0.5/z)(z-10)^2]], {z, 0, infinity}], {w, 0, a}] b is known and trying to solve for a where both w and z are independent variables. ********************************* 3) b = Integrate [Integrate [[[[(w)(z)^(3/2)]^(-1)]Exp[-5(Log(z))^2-[1/(10(w)(z))][(z)(w)-5)]^2]], {z, 0, infinity}], {w, 0, a}] b is known and trying to solve for a where both w and z are independent variables regards. cheers -- ----------------------------------------------------- Click here for Free Video!! http://www.gohip.com/freevideo/
