If sin θ = 3/5, then csc θ equals

If sin θ = 3/5, then csc θ equals

• A. 5/3
• B. 3/5
• C. -5/3
• D. -3/5

Answer: (A)

csc θ is the reciprocal of sin θ. So csc θ = 1 / sin θ. If sin θ = 3/5, then csc θ = 1 / (3/5) = 5/3. The sign follows sin, and since sin θ is positive, csc θ is also positive. The value is 5/3.
