## How do you integrate a surface integral?

You can think about surface integrals the same way you think about double integrals:

- Chop up the surface S into many small pieces.
- Multiply the area of each tiny piece by the value of the function f on one of the points in that piece.
- Add up those values.

## What is the Liate rule?

For those not familiar, LIATE is a guide to help you decide which term to differentiate and which term to integrate. L = Log, I = Inverse Trig, A = Algebraic, T = Trigonometric, E = Exponential. The term closer to E is the term usually integrated and the term closer to L is the term that is usually differentiated.

**What is the rule for integration by parts?**

In integration by parts, we have learned when the product of two functions are given to us then we apply the required formula. The integral of the two functions is taken, by considering the left term as first function and second term as the second function. This method is called Ilate rule.

**What is the formula of by part?**

The formula for integration by parts is ∫uv. dx=u∫v.

### What does surface integral calculate?

If the vector field F represents the flow of a fluid, then the surface integral of F will represent the amount of fluid flowing through the surface (per unit time). The amount of the fluid flowing through the surface per unit time is also called the flux of fluid through the surface.

### What is surface integral in mathematics?

In mathematics, particularly multivariable calculus, a surface integral is a generalization of multiple integrals to integration over surfaces. It can be thought of as the double integral analogue of the line integral. If a region R is not flat, then it is called a surface as shown in the illustration.

**Which rule is correct Ilate or Liate?**

In general the ILATE rule is used. However, LIATE is also equivalently correct.

**What is the formula of integration?**

Formula for Integration: \int e^x \;dx = e^x+C.
