Fiche explicative de la leçon: Limites par substitution directe

Dans cette fiche explicative, nous allons apprendre comment utiliser la méthode de substitution directe pour déterminer une limite. La limite d’une fonction en un point nous renseigne sur le comportement de la fonction au voisinage de ce point plutôt que sur sa valeur en ce point.

1.5: Evaluate Limits Using Substitution - K12 LibreTexts

One way to evaluate a limit analytically is by substitution. Substitution is a method of determining limits where the value that x is approaching is substituted into the function and the result is evaluated.

Limits by Substitution | Brilliant Math & Science Wiki

The substitution rule is a method of finding limits, by simply substituting x x with a a. The mathematical manifestation of this rule would be. \displaystyle {\lim_ {x\rightarrow a}f (x)=f (a)}. x→alimf (x) = f (a). Let's try out a few examples first. Find the value of \displaystyle {\lim_ {x\rightarrow-1}x^2} x→−1lim x2. This is simple.

Direct Substitution: Find Limits in Easy Steps

Direct substitution is just what the name implies: you directly substitute a given value into a limit. Probably the most intuitive way to find a limit is to look at a limit graphically (on a graphing calculator) or numerically (through a table).

2.3 The Limit Laws - Calculus Volume 1 - OpenStax

As we have seen, we may evaluate easily the limits of polynomials and limits of some (but not all) rational functions by direct substitution. However, as we saw in the introductory section on limits, it is certainly possible for lim x → a f ( x ) lim x → a f ( x ) to exist when f ( a ) f ( a ) is undefined.

4.7: Definite integrals by substitution. - Mathematics LibreTexts

Substitution for Definite Integrals. Substitution can be used with definite integrals, too. However, using substitution to evaluate a definite integral requires a change to the limits of integration. If we change variables in the integrand, the limits of integration change as well.

Lesson Explainer: Limits by Direct Substitution | Nagwa

In this explainer, we will learn how to use the direct substitution method to evaluate limits. The limit of a function at a point represents the behavior of the function near that point, rather than the value of the function at the point. Let us begin by recalling the formal definition of the limit of a function.
