Answer:

#r=c csctheta#

Explanation:

The relation between polar coordinates #(r,theta)# and Cartesian coordinates #(x,y)# is given by

#x=rcostheta# and #y=rsintheta#

The equation of a horizontal line is of the form #y=c#, where #c# is #y#-intercept, a constant.

Hence, in polar coordinates equation would be

#rsintheta=c# or #r=c csctheta#
