- Do not ping the Moderators, unless someone is breaking the rules.
- Do not ping the Helper Moderators, unless there is a conflict between helpers.
- Do not ping other members randomly for help.
- Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
- Wait patiently for a helper to come along.
- If the Helper has answered your question, remember to thank them with the Mathematics Ranks bot and close the thread with:

what do you think.
trig functions are periodic, so it’s gonna become inaccurate after some point
try graphing one on a software and see where it leads you

I think so yeah, you have a function of four variables that you try to minimize
That is:
$$L(a,b,c,d) = \sum_{(x,y) \in D} (y - f(x,a,b,c,d))^2$$
Where $$f(x,a,b,c,d) = a\sin(bx) + cx + d$$

And D is a dataset of points (x, y)
I don't know if there are closed forms of the minimizer
But typically you could get away with iterative optimization techniques like gradient descent or whatnot
