Final answer:
The reference angle for t = 4/3 is (3π - 4)/3 radians.
Step-by-step explanation:
To find the reference angle for t = 4/3, we need to determine the angle between the terminal side of t and the x-axis.
Since t = 4/3 is positive and lies in the second quadrant, the reference angle is the angle formed between the positive x-axis and the terminal side of t.
To find the reference angle, we subtract t from π radians (180 degrees).
π - t = π - 4/3 = 3π/3 - 4/3 = (3π - 4)/3
The reference angle for t = 4/3 is (3π - 4)/3 radians.
