comment Find multiple of 'radius' of square given angle of line.
@user1825860: $\csc(90)=1.11857$ so you are using radians. $90^\circ=\frac\pi2$ radians. As with any calculator, you need to set the mode to reflect the angular units you are using (degrees or radians).

$\min(|\sec(x)|,|\csc(x)|)$ looks good

comment Can rational numbers have decimals?
@BrianS: From the cited answer, the polynomial needs to be not only monic, but also all its coefficients need to be integers: "any rational number $x$ which satisfies $(2)$ with integer $c_k$ must be an integer". However, $2.25$ is not an integer.

does this assume that $f'$ is continuous?

There is a missing factor of $\frac43$ missing from your formula.
