• Start with the innermost function

• Ignore the inverse trig function

• Always use the unit circle

Why isn't the answer in quadrant 3?

• The answer is not in quadrant 3 as it has both coordinates zero.

• The answer is not in quadrant 3 because it does not have both coordinates negative.
• The answer is not in quadrant 3 it is not in the domain of the sine function.

• The answer is not in quadrant 3 because both coordinates are positive.
