This math topic focuses on the application of trigonometric identities to determine the correct signs of various trigonometric ratios for specific angles measured in degrees. Specifically, the problems require identifying how the signs (positive or negative) of trigonometric functions such as sine, cosine, tangent, cotangent, secant, and cosecant change based on the angle's position in different quadrants. This involves understanding and utilizing the rules of trigonometric functions across the four quadrants on the unit circle.
