B Relation between ##d## and ##\theta##

  1. Jun 25, 2017 #1
    I wish to find a closed form relation between ##\theta## and ##d## in the attached figure as a function of ##r##, the radius of the circle and ##s## the distance from the point ##p## to the center.
    Thank you.

    Can you please show your work so far? What part are you having trouble with?

    Is this question for schoolwork?

    Just right now, I had insight for how to solve it :)
    ##s^2=r^2+d^2+2 d r cos (a)##
    But ##a+\theta=\pi/2##.
    ##s^2=r^2+d^2+2 d r cos (\pi/2 -\theta)##
    rearranding, gives a relation between ##d## and ##\theta##.
