How to evaluate for sine using a calculator in radians sin

The video tutorial explains the difference between radians and degrees, emphasizing the concept of radians as the radius wrapped around a circle. It highlights the importance of setting calculators to radian mode for accurate calculations and provides an example of calculating the sine of an angle in radians.

What is the primary difference between radians and degrees?

• Radians are larger than degrees.

• Radians are based on the radius of a circle, while degrees are a division of a circle into 360 parts.

• Degrees are used in physics, while radians are used in mathematics.

• Radians are used for measuring time, while degrees measure angles.

How is the distance of one radian defined?

• As the circumference of the circle.

• As the diameter of the circle.

• As half the radius of the circle.

• As the radius of the circle wrapped around the circumference.

What should you ensure about your calculator when working with radians?

• It is set to degree mode.

• It is set to scientific mode.

• It is set to radian mode.

• It is set to basic mode.

What is the approximate sine value of 1.72 radians?

• 0.5

• 0.707

• 1.0

• 0.988

Why is it important to use the correct mode on your calculator when solving problems involving radians?

• To save battery life.

• To ensure the calculator displays results in fractions.

• To avoid incorrect results due to mode mismatch.

• To make the calculator run faster.
