The point o moves to o' along the x axis to a distance 'x'.
The point 'a' moves on a circle and reaches 'b' such that oa = o'b. angle subtended by 'a' and 'b' is 'θ '
The point 'c' moves through the same angle 'θ ' as of a . point 'c' finally reaches point 'd' .
point 'e' is fixed on the 'y' axis.
I want to find the relation between 'x' and *(ce - de).
