Question #e34e6 Precalculus 1 Answer Binayaka C. Nov 17, 2017 #(C) : theta = pi/4# Explanation: From rectangular to polar form ,#x=rcos theta # and #y=r sin theta # where #r# is the distance from the origin to the point, and #theta# is the angle measured from the positive 'x' axis to the point: Given #y=x :. cancelrsin theta= cancelr cos theta# or #sin theta= cos theta or sin theta/cos theta=1 # or #tan theta= 1 ; tan (pi/4)=1 :. theta = pi/4# #(C) : theta = pi/4# [Ans] Answer link Related questions How do I determine the molecular shape of a molecule?
