Math Problem Statement

so a figure with an angle of 300 degrees on a circle in standard position

Solution

A figure with an angle of 300 degrees in standard position on a circle is described as follows:

  1. Initial Point: The angle starts at the positive xx-axis, which is the standard reference line for angles in standard position.

  2. Direction of Rotation: Since the angle is positive, the rotation is counterclockwise from the positive xx-axis.

  3. Magnitude of Rotation: A full circle corresponds to 360360^\circ, so an angle of 300300^\circ means you rotate counterclockwise from the positive xx-axis by 300 degrees, which is 60 degrees short of a full circle.

  4. Reference Angle: The reference angle, which is the acute angle formed with the nearest axis (here the xx-axis), is 360300=60360^\circ - 300^\circ = 60^\circ.

  5. Quadrant: Since 300300^\circ is between 270270^\circ and 360360^\circ, the terminal side of the angle lies in the fourth quadrant.

  6. Coordinates of the Terminal Side: The terminal side intersects the unit circle. For an angle of 300300^\circ, the corresponding coordinates on the unit circle are: (cos(300),sin(300))=(12,32).\left(\cos(300^\circ), \sin(300^\circ)\right) = \left(\frac{1}{2}, -\frac{\sqrt{3}}{2}\right). These values represent the cosine and sine of the angle, respectively.

Summary:

  • Quadrant: Fourth quadrant
  • Reference Angle: 6060^\circ
  • Coordinates on Unit Circle: (12,32)\left(\frac{1}{2}, -\frac{\sqrt{3}}{2}\right)

Here are 5 related questions to deepen your understanding:

  1. What is the reference angle for an angle of 240 degrees in standard position?
  2. How do you find the sine and cosine of an angle in standard position?
  3. What is the terminal side of an angle, and how does it relate to the unit circle?
  4. Can you convert 300 degrees into radians? What is its equivalent in radians?
  5. How do positive and negative angles differ in terms of rotation on the unit circle?

Tip: The reference angle is always the smallest angle made with the xx-axis, and it helps simplify calculations for trigonometric values.
