Draw and use graphs of y = a sin bx + c, y = a cos bx + c and y = a tan bx + c. Graphs are drawn over a given domain, in degrees or radians. For y = a tan bx + c, clearly label the x-coordinate of any asymptote. Use a as a positive integer, b as a simple fraction or integer, and c as an integer; simple fractions have denominator 2, 3, 4, 6 or 8 only.
