This math topic focuses on determining the signs of trigonometric ratios—specifically sine, cosine, and tangent—for given angles in radian measure. It exercises the ability to understand how these trigonometric functions behave in different quadrants of the unit circle. The problems include identifying the correct signs of the trigonometric ratios for specific angles expressed in radians, thereby practicing and applying knowledge of trigonometric identities and quadrant sign rules.
