Packet 03 Algebr2 / Trigonometry To the right is the same circle as the previous page. a) Points C and E share the same y-coordinates. ib.mat is the sum of their angles of rotation from K? b) Points D and F share the same y-coordinates. mat is the sum of their angles of rotation from K? c) Points G and J share the same y-coordinates. What is the sum of their angles of rotation from K? d) Points H and I share the same y-coordinates. What is the sum of their angles of rotation from K? e) We saw that there was one pattern for x-coordinate pairs in the last assignment. How many patterns are there here for y-coordinate pairs? Can you come up with a rule? Ill. Answer the following questions with respect to the circle above: g) Given the point M on the unit circle has coordinates (a, b). If M is rotated 90 degrees, find the new coordinates: h) If M is rotated 180 degrees, find the new coordinates:
