This math unit advances through various aspects of trigonometry, beginning with foundational skills in identifying the signs of trigonometric ratios in different quadrants, then applying these skills to solve problems involving specific angle measures. As students progress, they delve into the unit circle and apply the Pythagorean identity to convert dimensional measurements into sine and cosine values using radians. The unit further develops with detailed exploration and verification of trigonometric identities involving the Pythagorean theorem, such as confirming the relationships between squared functions of sine, cosine, tangent, secant, cosecant, and cotangent. Toward the end of the unit, students apply these identities in more complex scenarios, solving for one trigonometric function using another while considering the quadrant's influence on the sign of the result. The culmination of the unit challenges students with problems that require advanced manipulation and simplification of trigonometric expressions, essential for higher mathematics and calculus.Skills you will learn include:
