A Particle travels on the x-axis so its velocity at time t is given by v(t)=1/2-cos(t) meters per second, where t is between 0 and 2pi, inclusive. . A. For what values of t is the particle moving to the right?. B. If the particle starts at x=3, what is the final position of the article?. C. What is the total distance traveled by the particle?. D. When t=pi/4, is the speed of the particle increasing or decreasing?
