Let P(x, y) be the terminal point on the unit circle determined by t.?

sin(t)=____

cos(t)=___

tan(t)=____

1 Answer

  • sin t = y-coordinate of the point on the unit circle … so sin t = y

    cos t = x-coordinate of the point on the unit circle … so cos t = x

    tan t = y-coordinate / x-coordinate = y/x
