convert each point,P(x,y)to the ordered pair P(r cos theta ,r sin theta).round all valuas of r to one dicimal place and all values of theta to the nearste degree.
I will do a), you do the rest
for (4,6), r^2= 4^2+ 6^2 = 52
Ø = appr 56.3°
so (4,6) ---> (√52cos56.3 , √52sin56.3)
= appr (7.2cos56° , 7.2sin56°)
AR U SURE ?
Did you want the ordered pair (4,6) expressed in polar form?
I was wondering why you asked for the form
(rcosØ, rsinØ) since that is simply the equivalent of (x,y)
e.g. my answer of (7.2cos56 , 7.2sin56) = (4.026 , 5.969) or (4,6)
if you want it in the polar form (r, Ø)
then (4,6) ---> (7.2 , 56°)
however, that is not what you had asked for.
