Convert the rectangular coordinates (v3 1) into polar coordinates ( 6) so that o and (i) (2 ) o (2 (m) (2 1 (iv) (2 ) (-2블) suppose a linear system of three equatione in three variables is being solved by making use of elementary row operations and we arrive at the tollowing matrix what does it mean? () that (t. r,0).er is a solution. (ii) that 〔t, t, r) , t. r e r is a solution. (ii) that it -2.1 -1,t.)te risa solution. iv) the original system of equation has no solution v) none of the above
