In the perspective of Philosophy, the answer is yes. Say, arithmetic is something that you are using almost everyday. When you pay your fare for a jeepney ride, you absolutely use math.
If your question is exclusive only to your specialization, you have to understand that in the actual field, only 5% of those knowledge will be repeatedly use. The remaining 95% will be stocked for a while before you can use.
For example, an electrical engineer will not always compute the electric field by the power cables installed in a 20-storey building. A pharmacist most of the time uses math especially if they are employed in Mercury dru, and so on.
In my case, since my course in College covers all areas in technology, from computer science, engineering, social science, communications, theoretical science, etc. I am using the knowledge I learned in college almost everyday. But mind you this, I am not practicing my specialization.
