Use cofunction identities and trig identities to find the indicated trig functions

The video tutorial explains the properties of the sine function, focusing on how to evaluate the sine of a negative angle. It discusses the concept that the sine function is odd, meaning the sine of a negative angle is the negative of the sine of the angle itself. The tutorial walks through the process of determining the sine of an angle given the sine of its negative counterpart, using the example of sine(-T) = 3/8 to find sine(T) = -3/8. The explanation is aimed at helping viewers understand the odd function property of sine and how to apply it in calculations.

What is the primary characteristic of the sine function when dealing with negative angles?

• It becomes negative.

• It remains unchanged.

• It becomes positive.

• It doubles in value.

If sine(-T) equals 3/8, what is the value of sine(T)?

• 1

• 0

• -3/8

• 3/8

How does the sine of a negative angle compare to the sine of a positive angle?

• They are both positive.

• They are unrelated.

• They are opposites.

• They are equal.

What is the result of evaluating sine(-T) if sine(T) is known to be -3/8?

• 3/8

• 1

• -3/8

• 0

What does it mean for the sine function to be an odd function?

• sine(-T) = 2sine(T)

• sine(-T) = 0

• sine(-T) = -sine(T)

• sine(-T) = sine(T)
