What is the exact value of cot(5pi/6)?

  • Math -

    If you draw the angle, then draw a line down to the x axis, you will find that your reference angle is pi/6.

    tan(pi/6) should be a memory value; cot is its reciprocal. Remember that your angle is in Quadrant II.

  • Math -

    I'm sorry, I'm still confused :s

  • Math -

    I cannot post images here - you'll have to draw it yourself.

    1. Draw the units circle, then draw the angle 5pi/6.

    2. draw a line from that angle to the x axis

    3. The angle of the resulting triangle is your reference angle.

    Can you get that far?
