CBSE Class 12 Mathematics 2026 Main Paper 65/4/3 · Question 1 (Inverse Trigonometric Functions)

Which inverse trigonometric function does the graph represent?
Decreasing curve with endpoints (−1,π) and (1,0), crossing the y-axis at π/2.
Decreasing curve with endpoints (−1,π) and (1,0), crossing the y-axis at π/2.

✅ Step-by-Step Solution

Final Answer: arccos x
  1. The curve has domain [−1,1], decreases, and maps −1 to π and 1 to 0. This is the principal inverse cosine.
