Trigonometry questions please help! What are the coordinates of the terminal point determined by theta= 7pi/6 ? Where do i start in this question? Also I am confused with these Sketch a unit circle and label the terminal points corrsponding to theta=pi/4, 3pi/4,5pi/4, 7pi/4. Include the oordinates of each point? Please explain how to do this to me.

    `What are the coordinates of the terminal point determined by theta= 7pi/6 ?` I think they are implying that this terminal point lies on the unit circle

    look at the unit circle. Find the angle 7pi/6. What is the corresponding point on the unit circle?

    I think 5pi/6 is the corresponding point on the unit circle.

    `I think 5pi/6 is the corresponding point on the unit circle. ` that's incorrect

    the third quadrant circle is 7pi/6 and the one in the 2nd quadrant is 6pi/6

    is that not the terminal point, what is a terminal point anyways?

    it's the point that lies on the unit circle

    look at this unit circle http://etc.usf.edu/clipart/43200/43215/unit-circle7_43215_lg.gif

    what point corresponds to 7pi/6 hint: it has square roots in it

    oh so the corresponding terminal angle is pi/6 and the points are (sqrt3/2. 1/2)
