How do you convert #theta= pi/4# to rectangular form? Trigonometry The Polar System Converting Between Systems 1 Answer P dilip_k · MeneerNask Mar 12, 2016 y=x Explanation: if #(r,theta)# be the polar coordinate corresponding to the rectangular coordinate (x,y) of a point. then #x= rcosthetaand y =rsintheta # #:.y/x=tantheta# here #theta =(pi/4)# So #y/x=tan(pi/4)=1# #=>y=x# Answer link Related questions How do you convert rectangular coordinates to polar coordinates?
