How to evaluate for cosecant using a calculator in radians

The video tutorial explains the relationship between sine and cosecant, emphasizing that they are reciprocal functions. It describes how sine is represented by the y-coordinate on the unit circle, while cosecant is the reciprocal of sine. The tutorial also demonstrates how to calculate cosecant using a calculator by inputting the reciprocal of the sine function, providing an example calculation for clarity.

What is the relationship between sine and cosecant?

• Cosecant is the reciprocal of sine.

• Sine is the reciprocal of cosecant.

• They are equal to each other.

• They are unrelated.

How is the sine of an angle represented on the unit circle?

• By the Y coordinate of the intersection.

• By the X coordinate of the intersection.

• By the radius of the circle.

• By the angle itself.

If the sine of an angle is 0.5, what is the cosecant of that angle?

• 0.5

• Undefined

• 1

• 2

Why might you not find a cosecant function on a calculator?

• Because it is the reciprocal of the sine function.

• Because it is not used in calculations.

• Because it is the same as the sine function.

• Because it is not a standard trigonometric function.

What is the approximate value of cosecant for an angle with sine 1.72?

• 1.011

• Undefined

• 1.72

• 0.58
