I am having some trouble understanding Math.tan() and Math.atan() and Math.atan2().

I have basic knowledge of trigonmetry but the usage of SIN, COS, and TAN etc for game development is very new to me.

I am reading on some tutorials and I see that by using tangent we can get the angle in which one object needs to be rotated by how much to face another object for example my mouse. So why do we still need to use atan or atan2?

I've heard many times that all programming is really a subset of math. Some suggest that OO, at its roots, is mathematically based. I don't get the connection.
