Aparticle travels clockwise on a circular path of diameter r, monitored by a sensor on the circle at point p; the other endpoint of the diameter on which the sensor lies is q. let theta be the angle between the diameter pq and the line from the sensor to the particle. let c be the length of the chord from the particle's position to q. complete parts a and b below. a. calculate d theta/dc b. evaluate d theta/dc with c=0
