Hi, I am having some difficulty understanding what is going on with the TI-84 complex number calculation in switching between rectangular and polar coordinates, hopefully someone can clarify this for me. For example, take the term 6<30 (6 angle 30). When I calculate this by hand going from polar to rectangular I get 5.196 + 3i. However, if I try to switch 6<30 into rectangular coordinates with my TI-84 I get 0.926 + 5.93i. Can anyone explain to me what is happening? Thanks in advance!
