How to solve
For y = a sin(bx), amplitude is |a| and period is 2π/|b|.
Steps
- Amplitude: peak height from the midline (= |a|).
- Period: horizontal length of one full wave (= 2π/|b|).
- Enter periods as 2pi or pi.
Example
y = 3 sin(2x)
- Amplitude 3.
- Period 2π/2 = π.
Answer: 3 or pi
How to type answers
- Period: 2pi or pi
