In a unit circle, 0 = 180°. Identify the terminal point and sin 0. O A. Terminal point: (0, -1); sin = -1
O B. Terminal point: (0, -1); sin = 0
O c. Terminal point: (-1,0); sin 0 = 0
D. Terminal point: (-1,0); sin 0 = -1

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
