Limit calculator evaluates the limit values of a function with respect to the input variable x. Analyze positive and negative limits of any calculus function with either single or multi variables.
Also, the calculator supports \(\frac{0}{0}\) and \(\frac{\infty}{\infty}\) limit problems to show you complete steps with visual representation. Just enter the function and see its behaviour at a certain limiting point.
“Limit defines the behavior of a function at a certain point for any input change”
Limit notation represents a mathematical concept that is based on the idea of closeness.
The calculator follows the same technique and assigns values to certain functions at points where no values are defined. It does this all in such a way as to be consistent with proximate or near values.
Limit calculator with steps works by analyzing various limit operations. These laws can be used to assess the limit of a polynomial or rational function manually as well.
Additionally, there are certain conditions for some rules and if they are not satisfied, then the rule cannot be used to validate the evaluation of a limit. Among these rules include:
| Rules | Expressions |
| Sum/Difference Rule | limx→b[f(x) ± h(x)] = limx→b[f(x)] ± limx→b[h(x)] |
| Power Rule | limx→b[f(x)n] = [limx→b[f(x)]]n |
| Product Rule | limx→b[f(x) * h(x)] = limx→b[f(x)] * limx→b[h(x)] |
| Constant Rule | limx→b[k] = k |
| Quotient Rule | limx→b[f(x) / h(x)] = limx→b[f(x)] / limx→b[h(x)] |
| L'Hopital's Rule | limx→b[f(x) / h(x)] = limx→b[f'(x) /h'(x)] |
Evaluate the limit of the function below:
\(\lim_{x \to 3} 4x^{3}+6x{2}-x+3\)
Solution:
Here we will be using the substitution method:Apply a limit to each and every value in the given function separately to simplify the solution:
\(= \lim_{x \to 3} \left(4x^{3}\right)+\lim_{x \to 3} \left(6x^{2}\right) - \lim_{x \to 3} \left(x\right) + \lim_{x \to 3} \left(3\right)\)
Now write down each coefficient as a multiple of the separate limit functions:
\(= 4 * \lim_{x \to 3} \left(x^{3}\right)+6 * \lim_{x \to 3} \left(x^{2}\right) - \lim_{x \to 3} \left(x\right) + \lim_{x \to 3} \left(3\right)\)
Substitute the given limit i.e;
\(\lim_{x \to 3}\):
\(\lim_{x \to 3} 4x^{3}+6x{2}-x+3 = 4 * \left(3^{3}\right) + 6 * \left(3^{2}\right) - 3 + 3\)
Simplify to get the final answer:
\(\lim_{x \to 3} 4x^{3}+6x{2}-x+3 = 4 * 27 + 6 * 9 - 3 + 3\)
\(\lim_{x \to 3} 4x^{3}+6x{2}-x+3 = 108 + 6 * 9 - 3 + 3\)
\(\lim_{x \to 3} 4x^{3}+6x{2}-x+3 = 162\)
Using The Substitution Method:
\(\lim_{x \to 0} \left(\frac{sin x}{x}\right)\)
\(= \frac{sin 0}{0}\)
\(= \frac{0}{0}\)
Which is an indeterminate form. So here we will be applying l’hopital’s rule: Before we move on, we have to check whether both the functions above and below the vinculum are differentiable or not.
\(\frac{d}{dx} \left(sin x\right) = cos x\)
\(\frac{d}{dx} \left(x\right) = 1\)
Moving ahead further now:
\(\lim_{x \to 0} \left(\frac{cos x}{1}\right)\)
\(= \frac{cos 0}{1}\)
\(= 1\)
