Choose the point on the terminal side of -210 degrees. where do i begin?

zepdrix (zepdrix):

`Choose the point` do you have a picture or something that goes along with this question?

OpenStudy (anonymous):

No, it's a multiple choice question, and that's the only information given

zepdrix (zepdrix):

What are the choices? :P

OpenStudy (anonymous):

A. (-1,1) B. (-1, sqrt3) C. (sqrt3,-1) D. (-sqrt3,1)

|dw:1402007337531:dw|The minus on our angle tells us so spin `clockwise`. Here is -210 degrees.

OpenStudy (anonymous):

so -1,sqrt3?

zepdrix (zepdrix):

We can eliminate C immediately since it's not in the second quadrant. You're going with B? Ummm let's see..

OpenStudy (anonymous):

I just thought that is what it would be from the graph

zepdrix (zepdrix):

sqrt(3) is `larger` than 1. If you look at the graph, our y coordinate should be `smaller` than our x coordinate, yes?|dw:1402007666273:dw|
