Convert the rectangular coordinates (4√3,−4) to polar form. Let r>0 and 0≤θ<2π.
Enter coordinates as simplifed fractions or radicals in simplest form
You have a point (x, y) and, I'm assuming, you want to convert it into r·cis( theta) form.
If you do: r = sqrt( x2 + y2 )
and theta = tan-1( y/x ).
Since the point ( 4sqrt(3), -4 ) is in the fourth quadrant, make certain that your angle is also in the fourth quadrant.
