.

Each student must know these values as a multiplication table : open your textbook in Trigonometry.

So, when you ask tutors about these values, it is the same as to ask them to repeat a multiplication table
one more time just specially for you.

Study, understand, draw and label the Unit Circle. Everything will then be in place and you can simply refer to it.
