Unexpected Result of Sym instead of SymFunction #53

Closed tomaklutfu closed 3 months ago

tomaklutfu commented 3 months ago

The constructors mentioned in this line return Sym objects instead of SymFunction but what is the use of them? The callabality is broken if Sym object is used since f(t), then, returns the object f but silently it is changed to t. Then, it causes diff(f(t), t) to return 1.

Yes, the issue is in calling v(t) for such objects. I need to catch that case. Thanks for letting me know.

54 works around this. Thanks
