After completing one revolution starting from the initial line, point A is observed to have coordinates () on the unit circle. Using that information, please answer the following questions:

(i) Calculate all 6 values of the trigonometric functions (clearly state the formulae used to calculate these functions). (ii) Determine the quadrant in which the point lies and provide the reason. (iii) Calculate the angle formed by point A and the reference angle with the positive X-axis.
