In mathematics, the Maclaurin series is a way of representing a function as a power series. It is named after Colin Maclaurin, who first published it in 1742. The Maclaurin series for sin(x)/x is:
$$\frac{\sin(x)}{x} = 1 – \frac{x^2}{3!} + \frac{x^4}{5!} – \frac{x^6}{7!} + \cdots$$
where $x!$ is the factorial of $x$.
Convergence of the Maclaurin Series
The Maclaurin series for sin(x)/x converges for all values of $x$. This means that the series can be used to approximate the value of sin(x)/x for any given value of $x$. The more terms that are used in the series, the more accurate the approximation will be.
Applications of the Maclaurin Series
The Maclaurin series for sin(x)/x has a number of applications. For example, it can be used to:
- Approximate the value of sin(x)/x for small values of $x$.
- Calculate the derivatives of sin(x)/x.
- Integrate sin(x)/x.
- Solve differential equations involving sin(x)/x.
