Angles on the unit circle repeat every 360\u2218360^\\circ, so angles greater than 360\u2218360^\\circ or negative angles can be converted to equivalent angles between 0\u22180^\\circ and 360\u2218360^\\circ.<\/p>\n\n\n\n<p>The angle 330\u2218330^\\circ lies in the fourth quadrant, where cosine is positive and sine is negative. Because tangent is sine divided by cosine, tangent in the fourth quadrant is negative.<\/p>\n\n\n\n<p>To evaluate the tangent at 330\u2218330^\\circ, the angle is related to the acute reference angle of 30\u221830^\\circ. Reference angles simplify trigonometric calculations by allowing the use of well-known values for acute angles.<\/p>\n\n\n\n<p>Knowing tan\u206130\u2218=13\\tan 30^\\circ = \\frac{1}{\\sqrt{3}}, the sign of tangent at 330\u2218330^\\circ is determined by the quadrant. Since the fourth quadrant tangent is negative, the answer becomes \u221213-\\frac{1}{\\sqrt{3}}, often rationalized to \u221233-\\frac{\\sqrt{3}}{3}.<\/p>\n\n\n\n<p>The reference angle is essential for understanding the relationship between the given angle and its trigonometric function value without needing a calculator or a unit circle chart for every angle.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Evaluate the following and indicate the reference angle 1.
