(q)'=sin (1 i)
is very close to (q)' = i
if i
is close to zero, which it appears to be in your plot.i*sin(1 q)
would come out of a TensoredLibrary

provides a ConcatLibrary

is nowhere close to i sin(1 q)
on the scale of the plot, where i is $\mathcal O(1e-2)$
Hi.
I am modeling an RLC circuit for alternating current (AC) using a data-driven approach. I use the variables current (i), charge (q), and frequency (f). The model is diverging from the analytical solution. Could someone please help me?"
My code:
My results:
(i)' = -41.144 1 + 436.417 sin(1 i) + -18908612133.648 sin(1 q) + -14.919 sin(1 f) (q)' = 0.997 sin(1 i) (f)' = 21.980 1
The term (f)' is correct. For (q)', it is somewhat accurate, It is necessary to remove sin(i) because, for my solution (q)' = i. However, (i)' is problematic. The term -18908612133.648 sin(1 q) is very large because according to the analytical solution, this is term should be i*sin(1 q).
I have tried several approaches to solve this issue, but so far I haven't found an effective solution.
