Question
please explain mathematically
Transcribed Image Text:In Calc. 3 applications, polar coordinates always obey:
(a) r = Vx2 + y² > 0
(b) 0<0 <2т.
tan (0) = y/x. Examine the Quadrants.
If (x, y) = (-V3, 1) , then findr and 0.
This must be in Quadrant II.
r =
+ 12 = V3 +1 = 2
1
tan (0)
/3)
Normally, this would give us -7/6, but this in Quadrant IV.
If we add 180°, we end up in Quad. II and 0 = 57/6.
