    Then find the inverse sine of 0 and and 360 to that answer repeatedly until you have 5 values.

    That is the unit circle. It is called the unit circle because the radius is 1 unit. The sin is like y.

    Your problem says to give 5 values for which the sin is 0. There are two of them right there: 0 degrees and 180 degrees. If we would go around the circle another time, we would come to 360 degrees and 180+360 which is 540 degrees. Are you with me?

    sorta.. so it would be 0,180,540?

  19. Mertsj Group Title

    0,180,360,540... Just keep adding 180 degrees because every 180 degrees, the y value (which is the sin) is 0.

    Or, instead of rotating counterclockwise, we could go clockwise and then the angles would be -180, -360, -540, ...

    The only way a fraction can be 0 is for the numerator to be 0. So the tangent is 0 whenever the sin is 0

    The sin of 180 degrees is 0. Therefore the tangent of 180 degrees is also 0 The sin of 0 degrees is 0. Therefore the tangent of 0 degrees is also 0 The sin of 360 degrees is 0. Therefore the tangent of 360 degrees is also 0 The sin of 540 degrees is 0. Therefore the tangent of 540 degrees is also 0.
