In a polar coordinate system, we select a point, called the pole, and then a ray with vertex at the pole, called polar axis. A point P in a polar coordinate system is represented by an ordered pair of numbers (r,0). If r>0, then r is the distance of the point from the pole; 0 is an angle formed by the polar axis and a ray from the pole through the point. 0 = 2 3TT P= (r, €) • P= (2, ) 0 = 0 Or=1 r=3 r= 5 Polar axis O Pole 8 = 7T 3TT Polar grid 1. Use table of values and plotting points in polar grid to graph the polar equation 2 Compare your result with results of other members of your group. r = sin 0 2. What type of graph did you get?

Convert the Cartesian coordinate (-2,-1) to polar coordinates,  0≤theta<2pi. round theta to nearest hundreths

I. Convert the following coordinate systems (it is essential to show the procedure). 1. (2,-6) 2. (8,-2) 3. (10, 45°) 4. (4, π/2) Cartesian to polar or polar to Cartesian
