Q: What is the value of cos(π/3)?
Solution:
cos(π/3) = 1/2.
Steps: 5
Show Steps
Step 1: Understand that π (pi) is a mathematical constant approximately equal to 3.14.
Step 2: Recognize that π/3 means we are dividing π by 3, which gives us an angle of 60 degrees.
Step 3: Recall the unit circle, which helps us find the cosine of angles.
Step 4: Find the cosine value for 60 degrees (or π/3) on the unit circle.
Step 5: Remember that the cosine of 60 degrees is 1/2.
