Evaluate tan θ and cot θ at unit-circle angles, including undefined points where the function has a vertical asymptote. Standards: CCSS HSF-TF.A.2 (tangent and cotangent via the unit circle). Each problem matches an answer in the design grid above. As students color in their answers, a symmetrical pattern appears. If the pattern looks right, the work is right — easy for students to catch mistakes and easy for you to spot-check at a glance. Works for classwork, homework, extra practice, extra cre
