How do we know the angle of 45 degrees is always equal to the square root of 2 over 2?

1 answer:

8 0

The question is not correct, you mean the the sine and cosine of 45 degrees is always square root 2 over 2.

Well you need to know how the sine and cosine are calculated. I would search in google for "sine and cosine in a unit circle". There is a very good Khan academy video that explains this in 10 minutes. Watch and learn :-)
