The graph would contain angles marked in the first and fourth quadrants. Option B is correct.
How to determine graph of trigonometric ratios.
Trigonometric ratios are relationships between the angles and sides of a right-angled triangle. Common ratios include sine, cosine, and tangent, representing the ratio of specific sides in the triangle.
Given
secθ = 2/1
secθ = 1/cosθ
2/1 = 1/cosθ
2cosθ = 1
cosθ = 1/2
θ = cos⁻¹(1/2)
θ = 60⁰, 300
Since the cos θ is positive and cosine is positive in the 1st and 4th quadrants, the graph would contain angles marked in the first and fourth quadrants. Option B is correct.
