Indefinite Integral

The indefinite integral represents a family of functions that have the same derivative.

Constant of Integration (C)

A constant of integration (C) is added to every indefinite integral because the derivative of a constant is always zero.

dx

The 'dx' indicates the variable with respect to which the integration is performed.

Anti-derivative

The anti-derivative of a function is another function whose derivative is the original function.

Integration by Substitution

A technique for finding the integral of a function by replacing part of the function with a new variable, simplifying the integral, and then substituting back to the original variable.

Substitution Variable (u)

In integration by substitution, we choose a new variable, usually represented by "u", to replace a part of the original function. The goal is to simplify the integral so that it becomes easier to integrate.

Finding du/dx

Finding the derivative of the substitution variable with respect to the original variable, often written as "du/dx". This is crucial for adjusting the integral after substitution.

Back-Substitution

Once you've integrated the simplified function in terms of "u", you need to substitute back the original variable (x). This ensures that the final result is expressed in terms of the original variable.
