If you're using a graphing calculator, make sure you're in DEG mode (not RAD). There probably is no button for the secant function, but remember that secant is defined as the reciprocal of cosine:

[tex]\sec19^\circ=\dfrac1{\cos19^\circ}[/tex]

So on your calculator, you'd type

1/cos(19)

and you should get about 1.0576.
