Function: y=sec(x)
Note: The U shapes of the secant graph are tangent to its reciprocal function, cosine, at cosines max and min locations.
- Thyere are vertical asymototes. The aymptote that occurs at /2 repeats every units.
- Period: 2
- amplitude: none, graphs go on forever in vertical directrions.
- The maximum values of y= cosx are minimum values of the positive sections of y= secx. The minimum values of y= cos x are the maximum values of the negative sections of y= sec x.
- The x-intercepts of y= cosx are the asymptotes for y= sec x.
Note: The U shapes of the secant graph are tangent to its reciprocal function, cosine, at cosines max and min locations.
First Graph: y= sec (x)
Second Graph: y= sec(x), y= cos (x)
Second Graph: y= sec(x), y= cos (x)
