How to find two coterminal angles for a large angle in radians

The video tutorial explains the concept of angles and revolutions, focusing on how to calculate coterminal angles. It demonstrates the process of breaking down angles into parts and finding both positive and negative coterminal angles by adding or subtracting multiples of 2π. The tutorial emphasizes understanding over memorization, encouraging learners to grasp the logic behind the calculations.

What is the value of a full revolution in terms of π?

• 6π

• 12π

• 2π

• 8π

How can you express an angle that is 5π/6 short of a full revolution?

• 12π/6 + 5π/6

• 6π/6 + 5π/6

• 10π/6 + 5π/6

• 8π/6 + 5π/6

What should you be cautious about when finding coterminal angles?

• Always subtracting 2π

• Using only positive angles

• Always adding 2π

• Memorizing plus or minus without understanding

If you subtract 12π/6 from 5π/6, what is the resulting angle?

• -5π/6

• -7π/6

• 5π/6

• 7π/6

What is the negative coterminal angle of 5π/6?

• -5π/6

• 7π/6

• -7π/6

• 5π/6
