One way is to memorize the signs for the different trig functions in the four quadrants. The way I remind myself of these formulas is to think of a point in the first quadrant (both x and y will be positive, so all sine and cosine values will be positive, as will tangent). u.s. bank national association nd

"WebUse reference angles to find the values of cos (150°) and sin (315°). Since 150° is in quadrant II, the reference angle for 150° is, 180°-150°=30° where, cos (30°)=. Also because 150° is in quadrant II, cosine is negative then, cos (150°)=. Since 315° is in quadrant IV, the reference angle for 315° is, 360°-315°=45° where, sin⁡ (45)°=.
