How can I launch a GameObject at a target if I am given everything except for its launch angle?
I modified DMGregory and Evorlor's solution a bit as I wanted a 3D arc and wanted to be able to apply a minimum speed if the provided speed wouldn't reach.

2d starship combat, hit chances based on bearing and speed (vector)?
You simply need a parametrical equation.
A good way to get how different the 2 ship's angle is is to use dot product on the ship's direction vector and the normalised version of the vector pointing ...

Unity C# - Rotate smoothly an object towards the direction given by input
I don't see why you need a coroutine; I think you need Quaternion.Slerp().
Unity give an example of what you want to do in its documentation.

Calculate aim angle dead zone range
Think of the gun as of being parented to the player (conceptually, it inherits player's transform (rotation)). That way, you only need to worry about the local angle (in local space, it's as if the ...

How do I apply real time physics to a 2D game in Java?
Don't worry about a package you want to use having more stuff in it than you need. It's unlikely a package will have just what you need... but no more than that.
What's more important is if it can do ...

I'd recommend that your method rotate counter-clockwise for positive ...

2d starship combat, hit chances based on bearing and speed (vector)?
Using the angles you provided as example, I took the liberty of assuming a few other data / scenarios.
Let's say you want a 100% hit chance when the angle difference is 0, and have the "good extremes"...
