WebMar 27, 2024 · In general, if a negative angle has a reference angle of \(30^{\circ}\), \(45^{\circ}\), or \(60^{\circ}\), or if it is a quadrantal angle, we can find its ordered pair, and so we can determine the values of any of the trig functions of the angle. Finding the Value of Trigonometric Expressions Find the value of the following expressions:
WebReference angles. A reference angle is an acute angle (<90°) that can be used to represent an angle of any measure. Any angle in the coordinate plane has a reference angle that is between 0° and 90°. It is always the smallest angle (with reference to the x-axis) that can be made from the terminal side of an angle. The figure below shows an ... WebHow do we (1) find a reference angle for each, and (2) find two coterminal angles, one positive and one negative, for each?” Reference Angles: -π/7 = 2π - π/7 = 14π/7 - π/7 = 13π/7 radians 3655° = 3655° - 10 * 360° = 3655° - 3600° = 55° Coterminal angles (positive and negative): 13π/7 + 2π = 13π/7 + 14π/7 = 27π/7 ra Continue Reading 1 Harvey Becker
