 The coordinates of 360 degrees/ 0 degrees are: (1,0) 360 degrees / 0 degrees 2Π zero degrees/ 360 degrees 2Π The coordinates of 270 degrees are: (0,-1) (0,-1) are the coordinates of: 270 degrees The coordinates of 360 degrees/ 0 degrees are: (1,0) (0,1) are the coordinates for: 90 degrees What do coordinates (0,1) represent? 90 degrees What are the coordinates for 180 degrees? (-1,0) (-1,0) represent the coordinates for how many degrees? 180 degrees What is the radian value for 180 degrees? Π What is the degree equivalent of the radian value Π ? 180 degrees 180 degrees is 1/2 of 360 degrees (a complete revolution) and so the radian value is half of two pi. The coordinates for 270 degrees are: (0,-1) (0,-1) are the coordinates for how many degrees? 270 degrees The radian value of 270 degrees is: 3Π/2 (0,1) are the coordinates for: 90 degrees What are the coordinates for 90 degrees? (0,1) 330 degrees is how many radians? 11Π/6 11Π/6 radians is how many degrees? 330 degrees 315 degrees is how many radians? 7Π/4 radians 7Π/4 radians is how many degrees? 315 degrees 300 degrees is how many radians? 5Π/3 radians 5Π/3 radians is how many degrees? 300 degrees 240 degrees is how many radians? 4Π/3 radians 4Π/3 radians is how many degrees? 240 degrees 5Π/4 radians is how many degrees? 225 degrees 225 degrees is how many radians? 5Π/4 210 degrees is how many radians? 7Π/6 7Π/6 is how many degrees? 210 degrees 210 degrees is how many radians? 7Π/6 (√3/2, -1/2) are cosine and sine in what quadrant? Quadrant IV Because the x-value (cosine) is positive and the y-value (sine) is negative, they are in the ... quadrant. (√2/√2) are cosine and sine for what degrees and radians? 45 degrees / Π/4 Because both have positive signs, they are in the first quadrant, Quadrant I, of the unit circle. (1/2, √3/2) are the cosine and sine for what degrees and radians on the unit circle? 60 degrees and Π/3 Because both have positive values, they are in the first quadrant, Quadrant I, of the unit circle. What are the coordinates for 270 degrees / 3Π/2 on the unit circle? (0,-1) They lie on the y-axis and y is a negative value. The coordinates (0,1) on the radian circle represent how many degrees and radians? 90 degrees and Π/2 y is a positive value and the coordinates lie on the y axis, opposite 270 degrees. What are the cosine and sine values for 120 degrees / 2Π/3? (-1/2, √3/2) The x-value will be negative and the y-value positive, which puts it in Quadrant II. (-√2/2, √2/2) are cosine and sine for what degrees and radians? 135 degrees and 3Π/4 radians The x-value is negative and the y-value is positive which puts the coordinates in Quadrant II. 150 degrees / 5Π/6 have what cosine and sine values? (-√3/2, 1/2) The negative x-value and positive y-value put the values in Quadrant II. (-√3/2, -1/2) are cosine and sine for what degrees and radians? 210 degrees and 7Π/6 Both x-value and y-value are negative which puts the degrees in Quadrant III. 5Π/4 and its corresponding 225 degrees have what cosine and sine? (-√2/2, -√2/2) Both x-value and y-value are negative which puts the degrees in Quadrant III. (-1/2,-√3/2) are cosine and sine for what degrees and radians? 240 degrees / 4Π/3 Both x-value and y-value are negative which puts the degrees in Quadrant III. 300 degrees / 5Π/3 have what cosine and sine on the unit circle? (1/2, -√3/2) The positive x-value and negative y-value put the degrees in Quadrant IV. (√2/2, -√2/2) are the coordinates for what degrees and radians on the unit circle? 315 degrees / 7Π/4 The positive x-value and negative y-value put the degrees in Quadrant IV. 330 degrees and 11Π/6 are represented by what cosine and sine on the unit circle? (√3/2, -1/2) The positive x-value and negative y-value put the degrees in Quadrant IV. (-√2/2, √2/2) are cosine and sine of how many degrees on the unit circle? 135 degrees Quadrant II. (-√3/2, 1/2) are cosine and sine of how many degrees on the unit circle? 150 degrees Quadrant II. (-√3/2, -1/2) are cosine and sine of how many degrees on the unit circle? 210 degrees Quadrant III. (-√2/2, -√2/2) are cosine and sine of how many degrees on the unit circle? 225 degrees Quadrant III. (1/2,-√3/2) are coordinates for how many degrees on the unit circle? 300 degrees. Quadrant IV (-1/2, √3/2) are cosine and sine for how many degrees on the unit circle? 120 degrees Quadrant II. (√3/2, 1/2) are the cosine and sine for how many degrees on the unit circle? 30 degrees Quadrant I. (√3/2, -1/2) are cosine and sine for how many degrees on the unit circle? 330 degrees Quadrant IV.
