Hi Valery. Use Ctrl+Shift+K for write D(x)(0), which means x'(0)

Best regards.

A pendulum ...

The exact solution needs some handwrite work.

Edited: a hard handwrite work. Previous version was wrong.

Correct solution -> pendulum v2.sm (13,73 KiB) scaricato 1462 volta(e).

Wrong solution -> pendulum.sm (13,88 KiB) scaricato 1468 volta(e).

Best regards.
