The point P(x, y) lies on the terminal side of an angle mc014-1.jpg = –60° in standard position. What are the signs of the values of x and y?

The sign value for x is positive and for y is negative. In standard position, the x point is at the origin, so the value will be 0. The terminal side is the line that moves to create the angle. At -60 degrees, the terminal side will be in the minus side of the y axis.

Considering the unit circle, it is found that:

  • The value of x has a positive sign.
  • The value of y has a negative sign.

What is the unit circle?

For an angle \(\theta\) the unit circle is a circle with radius 1 containing the following set of points: \((\cos{\theta}, \sin{\theta})\).

In this problem, we have an angle of -60º, which is equivalent to an angle of 360 - 60 = 300º, in the fourth quadrant, in which the cosine is positive and the sine is negative, hence:

  • The value of x has a positive sign.
  • The value of y has a negative sign.
