other 4 trig functions

• Tangent Cotangent (see p. 304)
• 3. If the a is positive, the graph takes the
  shape as shown on p. 304
• 4. If the a is negative, the graph
• of tan takes the shape of cot, and vice
  versa

Lesson Section 4.6 page 298Topic Graphs of
other 4 trig functions

• Secant Cosecant (see p. 304)
• 3. Find an x value exactly in the middle
  between two consecutive asymptotes
• 4. Plug that x-value into the equation,
• then plot the resulting point. If the point
  is above the x-axis (before any vertical shift),
  the U goes up. If the point is below the
  x-axis (before any vertical shift), the U goes
  down.
