Given y = A sin (Bx + C) + D
- amplitude is | A |
- period is [tex]\bold{\dfrac{2\pi}{\text{B}}}[/tex]
- phase shift is [tex]{-\dfrac{\text{C}}{\text{B}}}[/tex]
- vertical shift is D
A cos function is the same as a sin function.
A tan function has a period of π, so the period is [tex]\dfrac{\pi}{\text{B}}[/tex]
