The x-intercepts of y = cos(2x) in the interval 0 ≤ x < 2π are π/4 and 7π/4
The x-intercepts of y = cos(2x) are gotten when y = 0.
So, y = cos(2x)
cos(2x) = 0
Taking inverse cos of both sides, we have
cos⁻¹cos(2x) = cos⁻¹(0)
2x = π/2
Dividing both sides by 2, we have
x = π/4
So, the other angle in the range 0 ≤ x < 2π is x = 2π - π/4 = 7π/4
So, the x-intercepts of y = cos(2x) in the interval 0 ≤ x < 2π are π/4 and 7π/4
