Assuming you are integrating with respect to one of the three variables, you integrate normally. For example:
∫(x+y+z)dx
= ∫ x dx + ∫ y dx + ∫ z dx (Integral of the sum is the sum of the integrals)
= x^2/x + yx + zx + C
Or a harder one:
∫ (sin^2(y)+sqrt(z))/x dx
= (sin^2(y) + sqrt(z))*∫ 1/x dx (Factor out constants)
= ln(x)*(sin^2(y) + sqrt(z))
tl;dr: just do it normally with normal integration rules

To integrate a three-variable function, you need to perform a triple integral. This involves integrating the function with respect to each variable individually, in the order specified by the given problem. The result will be a scalar value representing the integral of the three-variable function over the specified region.

How the exponential logarithm and trigonometric functions of variable is different from complex variable comment?
The exponential function, logarithms or trigonometric functions are functions whereas a complex variable is an element of the complex field. Each one of the functions can be defined for a complex variable.
How do you integrate functions?
To integrate a function you find what the function you have is the derivative of. for example the derivative of x^2 is 2x. so the integral of 2x is x^2.
What do integrate mean?
In calculus, "to integrate" means to find the indefinite integrals of a particular function with respect to a certain variable using an operation called "integration". Synonyms for indefinite integrals are "primitives" and "antiderivatives". To integrate a function is the opposite of differentiating a function.
Is it true that functions take in values of the independent variable?
Sometimes. There need not be any independent variable - if the variables are all intercorrelated through feedback.
What are the three types of variables?
The three types of variables are: Independent: it is the one that you manipulate Dependent: the one that reacts to the changes in the independent variable and is measured in a experiment Control: all the other factors that could affect the dependent variable but are kept constant through out an experiment

How can you integrate a function by computer?
The best program I've found is Mathmatica. It's fairly easy to integrate a function on that program. Also, TI-89 will integrate functions.
Uses electrochemical signals to integrate and control body functions?
Nervous system
How can you integrate Kongregate API into Game Maker 8?
If it's in .dll form, you can integrate the .dll using the functions stated in the Game Maker Documentation.
How do you integrate functions?

What is a sentence using the word integrate?
"In the 1960's, many school districts began to integrate public schools." "The city plans to integrate their bus lines and streetcars into a single system." "Printed circuits can integrate many electronic functions into a single board."
Does the cardiac muscle coordinate regulate and integrate body functions?
No, the nervous tissue is actually what coordinates regulates and integrates body functions.

How do you get the median of a continuous random variable?
You integrate the probability distribution function to get the cumulative distribution function (cdf). Then find the value of the random variable for which cdf = 0.5.
Who was the first company to integrate marketing into their search engine?
It is difficult to say what the first company was to integrate marketing into their engine, but it seems to be Yahoo. They integrated advertising and targeted marketing into their functions.
What is Definition of law of variable proportion?
The law of variable proportion is basically a study of production functions. The factors used include fixed and variable factors.
What are Three types of variables?
Control Variable, Independent Variable, Dependent Variable.
