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.
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.
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.
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.
Sometimes. There need not be any independent variable - if the variables are all intercorrelated through feedback.
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
