Details

  • This message is generated when the unknown function is not specified in the form function[vars]. This makes it difficult to decide which unknown function is to be found.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[DSolve::baddv].

Examples

Basic Examples  (1)

The function y[x][x] is not specified clearly as a function of the independent variable x:

Wolfram Language code: DSolve[y'[x] == 1, y[x][x], {x}]

Replace y[x][x] in the second argument of DSolve with y[x]; then the example works:

Wolfram Language code: DSolve[y'[x] == 1, y[x], {x}]
