comment Analogue for Maple's dchange - change of variables in differential expressions
How about adding one more syntax dChange[expresion, rule, {oldVars}, {newVars}, {functions}] that will internally make use of CoordinateTransform instead of Solve? Then one can do something like Assuming[{r > 0, -Pi < θ < Pi}, dChange[D[f[x, y], x, x] + D[f[x, y], y, y] == 0, "Cartesian" -> "Polar", {x, y}, {r, θ}, f[x, y]]]

@Guesswhoitis. Yeah, I know, but InverseFourierTransform doesn't know 囧:i.stack.imgur.com/PGcPh.png

Module should be used instead of Block to avoid potential mistakes

@jlperla I managed to make a better implementation of bilateral Laplace transform, it can handle DE now, have a look!
