Question

Draw the angle given in degrees on the unit circle where 0 radians corresponds to the positive portion of the horizontal axis: -16pi/7

Answer 1

anyone ?

Answer 2

plz help me

Answer 3

plz help me

Answer 4

\(\bf \cfrac{16}{7}\implies \cfrac{7+7+2}{7}\implies \cfrac{\cancel{7}}{\cancel{7}}+\cfrac{\cancel{7}}{\cancel{7}}+\cfrac{2}{7}\implies 1+1+\cfrac{2}{7}
\\ \quad \\
2+\cfrac{2}{7}
\\ \quad \\
thus\qquad -\cfrac{16}{7}\implies -2\pi -\cfrac{2\pi }{7}\)

notice, a full CLOCKWISE cycle is \(-2\pi\) so just draw the remaining after the cycle
and then get the CLOCKWISE angle

Answer 5

shoot... actually that's backwards

Answer 6

notice, a full CLOCKWISE cycle is −2π so just draw the remaining after the cycle
and then get the COUNTER-CLOCKWISE angle

Answer 7

anyhow \(\bf -\cfrac{16\pi }{7}\implies -2\pi -\cfrac{2\pi }{7}\)
