### Dimensional analysis - application to logarithms

I read some nice threads about this topic: physics StackExchange maths StackExchange stats StackExchange However, it still puzzles me that logarithm of some physical quantity has no units. Example, ...
How do I decide the dimensions of a trigonometric quantity and a logarithmic quantity? For example, what are the dimensions for: $$\frac{C}{B} = \frac{D^2}{A} + \log \left(\frac{AC}{BD}\right)$$
