For y = 4·cos(3x), period = 2π/k. Enter the value of k.
Direct Answer: Period Calculation from Wave Frequency is defined by: 3. Period formula is T = 2π / B. Since B = 3, the period is 2π/3, so k = 3.
Detailed Step-by-Step Explanation:
Period formula is T = 2π / B. Since B = 3, the period is 2π/3, so k = 3.
