Need help...
secx=3.45 (0<=x<=2pi) (Accurate to 2 decimal places)
secx=-5.2 (0<=x<=2pi) (Accurate to 2 decimal places)
How do you do these questions?...i am getting mixed up by doing it on the calculator...use radian or degrees mode??...cos or cos-1?...and also about csc and cot too...can anybody explain thoroughly how to do them? (Maybe give more examples)
Thanks
