Trigonometry: polar coordinates help?
Need some help here please
1. the rectangular point are given. Find the polar coordinates (R, θ) of this point with θ expressed in radiant. Let R>0 and -2pi< θ<2pi
2. the letters X and Y represent rectangular coordinates, write the given equation using polar coordinates (r,θ)
A. 2r^2 sin (2θ)=1
B.2r^2 cos (2θ)=1
C. 4r^2 sin (2θ)=1
D. 4r^2 cos(2θ)=1
3.the letters X and Y represent rectangular coordinates, write the given equation using polar coordinates (r,θ)
A. r= 5/ cosθ + sin θ
B. r=5
C. r^2=5/ cosθ + sin θ
D. r^2=5
4. the letters r and θ represent polar coordinates. write the given equation using the rectangular coordinates (x,y)
r=8
0=?
