Dear all,
I'm pretty new with Mathematica and one of my first real attempt just failed :-(
HereS my input/output:
Solve[{(U/(T - U)) (Exp[-U x] - Exp[-T x]) + y Exp[-T x] ==
A, (U/(T - U)) (Exp[-U (x + d)] - Exp[-T (x + d)]) +
y Exp[-T (x + d)] == B}, {x, y}]
Solve::ifun: Inverse functions are being used by Solve, so some \
solutions may not be found; use Reduce for complete solution \
information. >>
Solve::svars: Equations may not give solutions for all "solve" \
variables. >>
{{y -> (-A \[ExponentialE]^(d T + T x) T +
B \[ExponentialE]^(d T + d U + T x) T - \[ExponentialE]^(d T)
U + \[ExponentialE]^(d U) U + A \[ExponentialE]^(d T + T x) U -
B \[ExponentialE]^(d T + d U + T x)
U)/((-\[ExponentialE]^(d T) + \[ExponentialE]^(d U)) (T - U))}}
----
What did I do wrong?
What's the correct syntax to solve this problem?
Many thanks in advance,
Cheers,
Jean
