Front

Sine and Cosecant

Back

Negative In Quad 1

Front

None

Back

The shortest repeating position of the graph of a periodic function

Front

cycle

Back

The horizontal line y=k in which the graph of a periodic function oscillates; Ex: The midline of g(x)= 2sin 4x+3 is y=3

Front

Midline

Back

One-half the difference of the miximum value and the minimum value of the graph of a trigonometric funtion, amplitude=1/2[1-(-1)]=1

Front

amplitude

Back

Negative in Quad 2

Front

Tangent, Cotangent, Cosine, Secant

Back

The number of cycles per unit of time, which is the reciprocal of the period; Example: The period of sin 2π is π, so the frequency is 1/π

Front

frequency
