13.5. Graphing Hyperbolic Functions
Enable hyperbolic functions by holding the e key. Set up Graph mode by going to Menu > Graph. Enter the equation as it appears in the problem. If the argument is longer than one term, enter it in parentheses. Make sure to set the desired scale (radians, fixed, degrees or auto).
Examples
Sketch the graph of each function below.
1) y = tanh x – 2
2) y = ½ sinh x – 1
3) y = cosh (½ x) –3
4) y = csch x – 3
5) y = ½ sech (3x) – 2
