Graphing secant and cosecant worksheet
Secant is one over cosine, so wherever cosine touches zero the secant flies off, and wherever cosine peaks the secant touches the same height. Sketch the cosine underneath first and the secant traces itself.

How to do these
Graph
- Cosine is zero at pi over 2 and at 3 pi over 2, so those are the asymptotes.
- Cosine peaks at 1 when x is 0 and at 2 pi, so the secant touches 1 there.
- Each piece opens away from the axis, never entering the band between -1 and 1.
The answer is Period , range excludes .
Where students go wrong
Drawing it through the middle like a sine wave. There is a band either side of the axis that a secant never enters, and every piece opens away from it.
Also called secant graphs, cosecant graphs, reciprocal trig graphs or plotting sec and csc.
