Question
hello, can you help to explain this question to me? like what is instant center, how come ve= omega times rec, how to find rec, how do we know it ccw, why is there a additional triangle adc formed. i asked another expert a similar question and they gave me another completely different method which i dont understand at all. why is there links involved? are they different question types ?
