The indefinite integral of $2x$ is $x^2+C$. In this context, the term 'indefinite integral' is simply another name for the antiderivative, representing the family of all functions whose derivative is $2x$.

Conditions: The expression being integrated is $2x$.; The result includes an arbitrary constant $C$.

To set up the integral for $I_y$ using a vertical strip, first express the differential area $dA$ in terms of $x$. A vertical strip has an infinitesimal width $dx$ and a height determined by the difference between the upper and lower boundary curves at position $x$.

Conditions: The region is bounded by curves that can be expressed as functions of $x$.; A vertical differential strip is chosen, meaning its width is $dx$.; The integration variable is $x$.

The indefinite integral is simply another name for the antiderivative. Both terms refer to the family of functions whose derivative is the given function, typically expressed with an arbitrary constant $C$.

Conditions: The context is introductory calculus focusing on reverse differentiation.; The function is continuous or differentiable on the interval of interest.

Integral notation is introduced early as a shorthand for antiderivatives to avoid writing cumbersome sentences. Its deeper geometric meaning, relating to areas under curves and sums of rectangles, will be motivated later when the course covers definite integrals.

Conditions: The current focus is on understanding antiderivatives.; The course will later cover definite integrals and areas under curves.

The notation $\int 2x \, dx$ is a compact way to ask for the antiderivative of $2x$ with respect to $x$. It represents the entire family of functions whose derivative is $2x$, which is written as $x^2+C$.

Conditions: The variable of integration is $x$.; The integrand is $2x$.

The general form of the antiderivative of $2x$ is $x^2+C$, where $C$ represents an arbitrary constant. This is because multiple functions differing only by a constant share the same derivative.

Adding a constant to a function does not change its derivative because the derivative of a constant is zero. When differentiating a sum, the constant term vanishes, leaving the derivative of the original function unchanged.

Conditions: The function is differentiable.; The added term is a constant (e.g., 1, $\pi$, or $C$).
