What is the value of cos^(-1)(0)?

What is the value of cos^(-1)(0)?

Correct Answer: π

Step 1: Understand what cos^(-1)(0) means. It is asking for the angle whose cosine value is 0.
Step 2: Recall the unit circle, which helps us understand the values of cosine for different angles.
Step 3: Identify the angles where the cosine value is 0. These angles are π/2 (90 degrees) and 3π/2 (270 degrees).
Step 4: The function cos^(-1) (also known as arccos) gives us the principal value, which is the angle in the range of 0 to π.
Step 5: Since π/2 is within the range of 0 to π and has a cosine value of 0, we conclude that cos^(-1)(0) = π/2.
