The purpose of integrating $\frac{\sin x}{x}$ is to find the area under the curve of the function. This can be useful in various applications of mathematics and physics.
The general process for integrating $\frac{\sin x}{x}$ involves using integration techniques such as substitution, integration by parts, or trigonometric identities to simplify the expression and then integrating it using the fundamental theorem of calculus.
Yes, there are two special cases when integrating $\frac{\sin x}{x}$: when the limits of integration include 0, and when the limits of integration are from negative infinity to positive infinity. In these cases, special techniques such as Cauchy's integral theorem may be required.
One common mistake is forgetting to include the constant of integration when using the fundamental theorem of calculus. Another mistake is incorrectly applying trigonometric identities or integration techniques, so it is important to double-check the steps taken during the integration process.
Integrating $\frac{\sin x}{x}$ can be used to solve problems involving periodic motion, such as finding the displacement or velocity of an object over a given time interval. It can also be used in engineering and physics to determine the work done by a force or the power output of a system.
