Q
Q: If y = cos^(-1)(1/2), what is the value of y?
Solution:
cos^(-1)(1/2) = π/3, since cos(π/3) = 1/2.
Steps: 3
Show Steps
Step 1: Understand that cos^(-1)(1/2) means we are looking for an angle y whose cosine value is 1/2.
Step 2: Recall the unit circle or the values of cosine for common angles. We know that cos(π/3) = 1/2.
Step 3: Therefore, we can conclude that y = π/3 because it is the angle whose cosine is 1/2.
