It means that you substitute one expression by another, as a step of the integration. When you do a substitution, you must not forget to also substitute the differential in the integral, for example the "dx" (if the variable integrated is "x"). You can find some examples on how to do this in the Wikipedia article on "integration by substitution".
It is a method in which the expression to be integrated, or a part of it, is replaced by another function. The purpose of the substitution is that, in the new form, integration is easier. It is important to remember that substitution changes the variable with respect to which integration needs to be carried out and so can also change the limits of integration.
i love wikipedia!According to wiki: In calculus, integration by substitution is a method for finding antiderivatives and integrals. Using the fundamental theorem of calculus often requires finding an antiderivative. For this and other reasons, integration by substitution is an important tool for mathematicians. It is the counterpart to the chain rule of differentiation.
There are no universal rules. However, there are a number of situations : quadratic functions and their square roots for which trigonometric substitutions are effective.
Quite simply that, like any general-purpose integration method, it works only for some specific cases. In this case, not all expressions can be simplified into something integrable simply by substituting something.
There is not Substitution Property of Congruence. There is, however, one for Equality, called the Substitution Property of Equality.
Assuming integration is with respect to a variable, x, the answer is 34x + c where c is the constant of integration.

I think you mean "u" substitution in integration. If an integral is too complicated to be solved using simple integration, part of the integral can be substituted for "u". Here is an example: ∫8x(4x²+7)³dx To solve this, you need a u substitution. Let's let u=4x²+7 Now, we can't still have x's in the equation if there is the new variable of u, so we need to change dx into du. To do this, we differentiate u. du=8xdx Luckily, we have that 8x in the integral already. After substituting the new u substitution in, the integral reads: ∫u³du Now, all we need to do is integrate! Once we integrate, we come up with u⁴/4 + C However, we have to bring it back into terms of x. If you recall u=4x²+7, so let's back-substitute. y = (4x²+7)⁴/4 + C And there you go! A successful u substitution!
