Question

can anyone explain how i solve this?

Find the radian measure for 2100 and its associated coordinate point on the unit circle. Then find the sin, cos, and tangent.

Answer 1

Where will 2100 be on the unit circle?What is the radian measurement for 2100 deg?

Answer 2

Let's do this easier 2100 deg on the radian circle would be the same as what deg? In other words if a circle is 360 deg we would divide 360 in 2100 and what we have as a remainder would be the location in deg on the unit circle.

Answer 3

360 x 5 = 1800. So we go around the unit circle five full times do you see this?

Answer 4

Then 2100 = the same spot as 300 deg. What is the radian measurement of 300 deg on the unit circle?

Answer 5

@Here_to_Help15 Im lost

Answer 6

so we have 1800

Answer 7

yes its 1800

Answer 8

that's it I'm done?

Answer 9

how do i find the sin cos and tang
