## What are the rules of antiderivative?

To find antiderivatives of basic functions, the following rules can be used:

- xndx = xn+1 + c as long as n does not equal -1. This is essentially the power rule for derivatives in reverse.
- cf (x)dx = c f (x)dx.
- (f (x) + g(x))dx = f (x)dx + g(x)dx.
- sin(x)dx = – cos(x) + c.

**Does an antiderivative always exist?**

For any such function, an antiderivative always exists except possibly at the points of discontinuity. There is always an answer (there is always a function whose derivative is the function given to you, provided it is continuous).

### What are the conditions for integration?

We can only integrate real-valued functions that are reasonably well-behaved. No Dance Moms allowed. If we want to take the integral of f(x) on [a, b], there can’t be any point in [a,b] where f zooms off to infinity.

**Which of the following is the process of finding the Antiderivatives of a given function?**

The process of solving for antiderivatives is called antidifferentiation, and its opposite operation is called differentiation, which is the process of finding a derivative.

## What have you learned about antiderivatives?

Antiderivatives are the opposite of derivatives. An antiderivative is a function that reverses what the derivative does. One function has many antiderivatives, but they all take the form of a function plus an arbitrary constant. Antiderivatives are a key part of indefinite integrals.

**What is the antiderivative of trig functions?**

Anti-derivatives of trig functions can be found exactly as the reverse of derivatives of trig functions. The anti-derivative of sinx is −cosx+C and the anti-derivative of cosx is sinx+C.

### Are Antiderivatives unique?

The antiderivative is therefore not unique, but is “unique up to a constant”. The square root of 4 is not unique; but it is unique up to a sign: we can write it as 2. Similarly, the antiderivative of x is unique up to a constant; we can write it as .

**What are antiderivatives used for in real life?**

In conclusion… Antiderivatives and the Fundamental Theorem of Calculus are useful for finding the total of things, and how much things grew between a certain amount of time.

## What is the importance of antiderivatives?

An antiderivative is a function that reverses what the derivative does. One function has many antiderivatives, but they all take the form of a function plus an arbitrary constant. Antiderivatives are a key part of indefinite integrals.

**When does an antiderivative of a function exist?**

Most functions you normally encounter are either continuous, or else continuous everywhere except at a finite collection of points. For any such function, an antiderivative always exists except possibly at the points of discontinuity.

### Why is holomorphy necessary for an antiderivative to exist?

Furthermore, holomorphy is a necessary condition for a function to have an antiderivative, since the derivative of any holomorphic function is holomorphic.

**How to characterize antiderivatives in the complex plane?**

One can characterize the existence of antiderivatives via path integrals in the complex plane, much like the case of functions of a real variable. Perhaps not surprisingly, g has an antiderivative f if and only if, for every γ path from a to b, the path integral

## Is there always an answer to the derivative of a function?

There is always an answer (there is always a function whose derivative is the function given to you, provided it is continuous). However, it may not be possible to express the answer in terms of familiar functions and operations. For example, the antiderivative of
