How do you convert #4=(x-4)^2+(y-5)^2# into polar form? Trigonometry The Polar System Converting Between Systems 1 Answer Shwetank Mauria Jul 21, 2016 #r^2-8rcostheta-10rsintheta+37=0# Explanation: Relation between polar coordinates #(r,theta)# and rectangular coordinates is given by #x=rcostheta#, #y=rsintheta#, #r^2=x^2+y^2# and #tantheta=y/x#. Hence #4=(x-4)^2+(y-5)^2# can be written as #x^2-8x+16+y^2-10y+25=4# or #x^2+y^2-8x-10y+37=0# or #r^2-8rcostheta-10rsintheta+37=0# Answer link Related questions How do you convert rectangular coordinates to polar coordinates?
