I am working on a Java algorithm to plot multiple hyperbolas at different angles. To help with that I googled and stumbled on this question.
My old and tired brain doesn't think I can do the substitutions properly (it seems easy but I think there might be some gotchas in there). So I would really benefit from the final answer, but I don't know how to bump somebody else's question to see if I can get someone to post the actual answer and not just hints on how to get to it.
Is it okay to bump somebody else's almost answered question?
How would I do that, if it's okay?
