Polar coordinates of a point are given Find the rectangular

Polar coordinates of a point are given. Find the rectangular coordinates of the point. The rectangular coordinates of the point are The rectangular coordinates of a point are given. Find polar coordinates of the point such that r > 0 and The polar coordinates are Convert the rectangular equation to a polor equation. Then use a rectangular coordinate rectangular equation. Chosse the correct rectangular equation for r = 18 cos theta below.

Solution

1.)Polar coordinates (6,90)=(r,q)

rectangular coordinates, x = r cosq,   y = r sinq

x=6 cos 90=0
y=6 sin 90=6

therefore, (0,6)
