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
