Unizor - Trigonometry - CSC Graph Problems

Before solving these problems review the graph of a function y=csc(x) and its basic properties: 1. Is it odd, even, periodical or neither? 2. What kind of symmetry, if any, does its graph have? 3. Does it equal to zero at some points and, if it does, where? 4. Does it have asymptotes and, if does, where? 5. What are its maximum and minimums and at what values of an argument? Then draw the graphs below and only after that watch the video. (a) y=csc(−x) (b) y=csc(3x) (c) y=csc(x/3) (d) y=3·csc(x) (e) y=csc((π/2)−x) (f) y=(−1/3)·csc(−3x−3π/2) (g) y=csc(2x) + csc(−x) (h) y=csc(x) + csc(x+π/2)
