Step-by-step explanation:
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

Answer:
39
Step-by-step explanation:
Put 5 where x is and do the arithmetic.
f(5) = (5+1)^2 +3 = 6^2 +3 = 36 +3
f(5) = 39
