Generally, this is not true. You can multiply two things together whenever you have defined a multiplication operation. As of now, there is no such operation defined over integrals which would allow us to talk about multiplying two integrals together (if there is one, then it is not widely known).

Integrating simple algebraic expressions

Integration is the inverse process to differentiation. Some people call it anti-differentiation. Instead of multiplying the power at the front and subtracting one from the power, we add one to the power and then divide by the new power.

No. They can't be split up. Instead, one can solve those integrals by Integration by Parts method or by Bernoulli's formula.

This rule means that you can pull constants out of the integral, which can simplify the problem. For example, the integral of 2x + 4 is the same as the 2 multiplied by the integral of x + 2. ... If you're integrating the constant times some function, you can pull the constant out of the integrals, that's really helpful.

The sum rule states that if you have two functions, the sum (additions) of their integrals always equals to the integral of their sum. In other words, if you have a string of additive functions, you can integrate them term by term. This rule applies to both definite integrals and indefinite integrals.

The most commonly used techniques for numerical integration are the midpoint rule, trapezoidal rule, and Simpson's rule. The midpoint rule approximates the definite integral using rectangular regions whereas the trapezoidal rule approximates the definite integral using trapezoidal approximations.Jul 25, 2021

Integration is the algebraic method of finding the integral for a function at any point on the graph. of a function with respect to x means finding the area to the x axis from the curve. ... integral will give the total distance at any given time.

The additive interval property says we can break up integrals into pieces (integrals on smaller intervals with the same integrand). Specifically, the integral over the interval [a,c] is the same as the sum of the integrals over [a,b] and [b,c] when a≤b≤c.

obtain the total area under the curve. Integration can therefore be regarded as a process of adding up, that is as a summation. ... The symbol ∫C tells us to sum the contributions along the curve C. This is an example of a line integral because we integrate along the line (curve) C.
