Question

how do you find the points of a terminal side given a degree such as -210?

Answer 1

please help me solve this problem.thanks

Answer 2

Do you know how to find a coterminal angle?

Answer 3

yes . by adding or subtracting 360

Answer 4

right. so what's the coterminal angle between 0 and 360?

Answer 5

it is 150

Answer 6

but im talking about the terminal. not the coterminal

Answer 7

It's really the same thing. coterminal angles are angles that have the same terminal side

Answer 8

so to find the point, you'd go to the unit circle and pick out the coordinates for 150

Answer 9

but that cant be the answer because the answer for coordinates to terminals usually have sqrt 3 or a 1 or both 1 and sqrt 3.

Answer 10

At 150 the coordinates are


But having a √3 or 1 isn't a necessity. If the angle was 45°, √2would be involved. Or you could have a point that isn't on the unit circle at all.
