Try to do something vs. Try doing something

Is there any differences between

Try to do

And

Try doing

Thank you in advence.

Solution 1:

Try to do is an effort to do something which you already know.

For example.

I tried to open the door.

I tried to call her.

Try doing is an effort based on more of a guess work.

For example.

Try hitting it with hammer, it might come off.

2. to test the effect or result of

To my (British English) ear, 'try to do' implies usage of the first meaning here, whereas 'try doing' implies the second.
