Question #b8860 Trigonometry The Polar System Converting Between Systems 1 Answer A. S. Adikesavan Jan 3, 2017 #x+ i y = < x, y> = < 4sqrt2, 4sqrt2># Explanation: The process of conversion to the cartesian form is #8 cis( pi/4)# #=8 < cos(pi/4), sin (pi/4)># #=8<1/sqrt2, 1/sqrt2># #=<8/sqrt2, 8/sqrt2># #=<4sqrt2, 4sqrt2># # = < x, y> # Answer link Related questions How do you convert rectangular coordinates to polar coordinates?
