Master how to convert an angle in radians to degrees

The video tutorial explains how to convert angles from radians to degrees. It begins with an introduction to the importance of understanding both formats. The instructor then details the conversion process, providing step-by-step examples. Special cases, such as non-fractional radians, are addressed, and the need for approximation in certain calculations is discussed.

Why is it important to convert radians to degrees?

• Radians are not used in mathematics.

• Degrees are the only unit used in physics.

• Radians are not a valid unit of measurement.

• Degrees are easier to visualize for most students.

What is the result of converting π/2 radians to degrees?

• 180 degrees

• 90 degrees

• 45 degrees

• 60 degrees

How do you simplify the conversion of 2π/3 radians to degrees?

• Use a calculator for direct conversion.

• Multiply 2 by 180, then divide by 3.

• Divide 180 by 3 first, then multiply by 2.

• Multiply directly without simplification.

What is the degree equivalent of 11π/6 radians?

• 330 degrees

• 360 degrees

• 180 degrees

• 300 degrees

How do you handle the conversion of a non-fractional radian like -4π?

• Convert it to a fraction by placing it over 1.

• Ignore the negative sign and convert directly.

• Use a different formula for non-fractional radians.

• Convert it to degrees first, then to radians.

What is the approximate degree value of 2 radians?

• 114.60 degrees

• 90 degrees

• 57.30 degrees

• 180 degrees

When converting π/17 radians, what is the approximate degree value?

• 20 degrees

• 10.59 degrees

• 30 degrees

• 15 degrees
