f[x_] = x^2 - 7*x + 10 g[x_] = Cos[3*x + 1/2*Pi] h[x_] = (x - 3)/(x + 2) Off[Solve::"ifun"] Solve[f[x] == y, x] Solve[g[x] == y, x] Solve[h[x] == y, x] Bobby Treat -----Original Message----- From: David [mailto:davidol at hushmail.com] To: mathgroup at smc.vnet.net Subject: [mg36210] [mg36189] How to use inversefunction How can I get mathematica to display the inverse of functions like: f(x) = x^2 - 7*x + 10 or f(x) = cos(3*x + 1/2*pi) or f(x) = (x - 3) / (x + 2) I'm having trouble getting the syntax right.
