Core Graphing Sine and Cosine

The period of a sine or cosine graph can be found using the formula $$\frac{2\text{π}}{B}$$ , where B is the frequency of the wave.

The amplitude of a sine or cosine graph is the maximum distance from the midline to the peak or trough of the wave.

$$\tan\frac{\text{π}}{6} = \frac{1}{\text{√3}}$$ .

The term is 'period'.

The amplitude is 4.

The frequency can be found using the formula $$B$$ in the equation $$y = A \text{sin}(Bx)$$ or $$y = A \text{cos}(Bx)$$ .

The period (T) is the reciprocal of the frequency (f): $$T = \frac{1}{f}$$ .

The phase shift is C units to the right if C is positive and to the left if C is negative.

Quadrantal angles are angles that are multiples of $$\frac{\text{π}}{2}$$ .

The range of both sine and cosine functions is from -1 to 1.
