1. given the curve that is described by the equation r = 3 cos θ, find the angle that the tangent line makes with the radius vector when θ = 120° a. 45° b. 30° c. 90° d. 60°

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.
