not sure, maybe try sol=DSolve[eqn,y[x],x], that is put y[x] there instead of just y.
Also try putting the equation explicitly into the DSolve command, for example like
sol=Dsolve[y''[x]==-y[x],y[x],x]

What is x. It looks like x is defined somewhere above. Try clearing x first and then re run your code
 

FAQ: Mathematica error when solving a DE -- "exceeded RecursionLimit"

What does the error "exceeded RecursionLimit" mean in Mathematica when solving a differential equation?

This error means that the code has reached its maximum limit for the number of recursive steps it can take while solving the differential equation. This limit is set by default in Mathematica to prevent infinite loops and ensure that the code terminates.

How do I fix the "exceeded RecursionLimit" error in Mathematica?

To fix this error, you can increase the RecursionLimit using the command $RecursionLimit = n, where n is the desired limit. Alternatively, you can rewrite your code to avoid recursive functions or use iterative methods instead.

Why does the "exceeded RecursionLimit" error occur in Mathematica?

This error can occur when solving a complex differential equation that requires a large number of recursive steps. It can also occur if the code contains a recursive function with no termination condition, causing it to run indefinitely.

Can I disable the RecursionLimit in Mathematica?

Yes, you can disable the RecursionLimit by setting it to $RecursionLimit = Infinity. However, this is not recommended as it can cause your code to run indefinitely if it contains a recursive function with no termination condition.

Are there any other ways to solve a differential equation in Mathematica without encountering the "exceeded RecursionLimit" error?

Yes, there are other methods such as using numerical solvers or built-in functions like DSolve or NDSolve that can solve differential equations without encountering this error. It is always good practice to explore different methods and choose the most suitable one for your specific problem.
