WebThe steps to find the reference angle of an angle depends on the quadrant of the terminal side: We first determine its coterminal angle which lies between 0° and 360°. We then see the quadrant of the coterminal … WebMar 27, 2024 · The angle −90^{\circ}\) is coterminal with \(270^{\circ}\). Therefore the ordered pair is (0, -1) and the cosine value is 0. Figure \(\PageIndex{2}\) We can also use our knowledge of reference angles and ordered pairs to find the values of trig functions of angles with measure greater than 360 degrees.
