Unit 8 Pre-Trig Graphs

Front

What is the midline of a trigonometric function?

Back

The midline is the horizontal line that runs through the middle of the graph of a periodic function, representing the average value of the function.

Front

What is amplitude in the context of trigonometric functions?

Back

Amplitude is the maximum distance the function reaches above or below its midline.

Front

What does the period of a function represent?

Back

The period is the length of one complete cycle of the function, indicating how often the function repeats itself.

Front

How do you calculate the amplitude of a sine or cosine function?

Back

The amplitude is calculated as the absolute value of the coefficient in front of the sine or cosine function.

Front

What is the relationship between degrees and radians?

Back

Degrees and radians are two units for measuring angles; 180 degrees is equivalent to π radians.

Front

What is the value of sin(90°)?

Back

1

Front

What is the value of cos(0°)?

Back

1

Front

What is the value of tan(45°)?

Back

1

Front

How do you find the value of y at a specific angle in a unit circle?

Back

The y-coordinate of a point on the unit circle at a given angle corresponds to the sine of that angle.

Front

What is the significance of 30° in trigonometry?

Back

30° corresponds to π/6 radians and has specific sine, cosine, and tangent values: sin(30°) = 1/2, cos(30°) = √3/2, tan(30°) = 1/√3.
