Answer:

tan(x) = 1

Explanation:

The red curve(s) are y=tan(x). The horizontal line is y=1, so the point(s) of intersection are where tan(x) = 1.

_____

Sine and cosine do not have infinite range.

The range of secant excludes (-1, 1), so the only remaining possibility for the red curve is tan(x).
