Answer:
- 2^(1/2) = √2
- 2^(2/3) = ∛(2^3)
- 3^(3/2) = √(3^3)
- 3^(1/2) = √3
Step-by-step explanation:
For each of these, you can make use of the form

Answer:
(- 1/2 , √3/2)
Step-by-step explanation:
t=20π/3
t' = 20π/3 - 6π = 2π/3 (120°) ... 2nd quadrant
If we start from (1,0) of unit circle, the coordinate of terminal point (x,y)
OF/OE = - cos 60° = x / 1 = - 1/2
FE/OE = sin 60° = y/1 = √3/2
