For sine its original value, 180-value, 360 +/- value
For cos its original value, 360 +/- value
For tan its original value, 180+value, 360 +/- value

So say you had trig (n) = x

Sin is 180-x
Tan is 180+x
Cos is 360 - x

If x is negative, you use the opposite trig you are using (so if it's sin something = -60 you'd use tan & cos which would get 240 and 300.)

Is that what you meant?

Hi there,

For this, you need to remember your four quadrants, and what is positive and in which quadrant.
