Question

Find the measures of two angles, one positive and one negative, that are coterminal with pi divided by six. thirteen pi divided by six; negative pi divided by six pi divided by six + 360°; pi divided by six - 360° seven pi divided by six; negative five pi divided by six thirteen pi divided by six; negative eleven pi divided by six

Answer 1

• thirteen pi divided by six (positive)
• negative eleven pi divided by six (negative)

Explanation:

The co-terminal angles are ...

• thirteen pi divided by six (positive)
• pi divided by six + 360° (positive)
• pi divided by six - 360° (negative)
• negative eleven pi divided by six (negative)

We usually don't like to mix degrees and radians, so the above answer selects a positive and negative angle that doesn't do that.
