I am trying to make some swift apps to do more advanced mathematical functions and am unsure where to find a few things, trig functions being a large part of it but also am unsure where to find things like numerical integration, let alone computer algebra based systems for these systems, I was wondering if/where all the advanced mathematical functions would be as searching through the developer docs are not really showing me anything.
Advanced Math Functions In Swift
Have you tried the Swift Numerics package?
Swift Numerics provides a set of modules that support numerical computing in Swift.
