Question

How do you graph `y=sec(1/2(x-pi/2))`?

Answer 1

graph{y=sec((1/2)(x-(pi/2))) [-14.89, 17.17, -6.56, 9.47]}

Explanation:

graph{y=sec((1/2)(x-(pi/2))) [-14.89, 17.17, -6.56, 9.47]}

This is how to graph it. Note that you need the secant graph memorized, then you just apply a vertical compression by a factor of `1/2` and a translation of `pi/2` to each point on the graph.
