Recall that an antiderivative of a function is another function whose derivative is the original function. In other words, if \(F'(x) = f(x)\), then \(F(x)\) is an antiderivative of \(f(x)\).
Identify the given function: \(f(x) = \sec^{2}x\).
Recall the derivative of the tangent function: \(\frac{d}{dx}(\tan x) = \sec^{2}x\).
Since the derivative of \(\tan x\) is \(\sec^{2}x\), an antiderivative of \(\sec^{2}x\) is \(\tan x\) plus a constant of integration, \(C\).
Write the general antiderivative as \(\int \sec^{2}x \, dx = \tan x + C\), where \(C\) is an arbitrary constant.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Antiderivative (Indefinite Integral)
An antiderivative of a function is another function whose derivative equals the original function. It represents the reverse process of differentiation and is expressed with an arbitrary constant since differentiation of a constant is zero.

Introduction to Indefinite Integrals
Basic Trigonometric Derivatives
Understanding the derivatives of trigonometric functions like tangent and secant is essential. For example, the derivative of tan(x) is sec²(x), which helps identify that the antiderivative of sec²(x) is tan(x) plus a constant.

Verification by Differentiation
After finding an antiderivative, differentiating it should return the original function. This step confirms the correctness of the antiderivative and reinforces the connection between differentiation and integration.
