Expanding on CFrames?

Could someone describe these in depth? I want to be able to reference these easier with a more vivid description for each one so I know what is most efficient and where.

CFrame:inverse()

CFrame:toWorldSpace(CFrame cf)

CFrame:toObjectSpace(CFrame cf)

CFrame:pointToWorldSpace(Vector3 v3)

CFrame:pointToObjectSpace(Vector3 v3)

CFrame:vectorToWorldSpace(Vector3 v3)

CFrame:vectorToObjectSpace(Vector3 v3)

CFrame:components()

CFrame:toEulerAnglesXYZ()
