Transcribed Image Text:The image presents a multiple-choice question about calculus, asking for the derivative of the inverse secant function, \(\sec^{-1} x\), with respect to \(x\). The provided options are:
**A)** \(-\sin x\)
**B)** \(\tan x \sec x\)
**C)** \(\frac{1}{x^2 \sqrt{1 - \left(\frac{1}{x}\right)^2}}\)
**D)** \(\frac{-1}{x^2 \sqrt{1 - \left(\frac{1}{x}\right)^2}}\)
These options represent possible expressions for the derivative of \(\sec^{-1} x\).
