Name --------------- Redefining the Trigonometric Functions Remember -----------------------------. 1. ln the coordinate plane, if Р(х, у) is а point оп а circle with center at the origin and radius r, then: sin8= у, cos8= х, tanO= У г г х у 2. The function values will Ье positive or negative depending оп the quadrant for the terminal side of 8. у QI: AII positive 61 N I �LL п QII: Sin positive � QIII: Тап positive А S QIV: Cos positive х � 6JТ х т с �s ш IV .S�C- Reciprocals are positive where the basic functions are positive. Use the information in each cell to determine the quadrant for angle 8. о, cose < sin8 > О, tan8 > О is in 1 cos8 > О, sin8 < О у is in sin8> is in е cot8 < О, sec8 > О is in cote > о, sin8 < О 8is in О sec8< О, tan8 > О is in '' cot8 < О, csc8 > О 8is in О . е а csce > о, cose < is in Q .
