Did you know that the integral of \( \sqrt{x} \) is commonly seen in calculus, especially in physics when dealing with motion? The process involves applying the power rule for integration, which states you can raise the exponent and divide by the new exponent. So when you see \( \sqrt{x} \), or \( x^{1/2} \), you just need to apply this rule to find that \( \int \sqrt{x} \, dx = \frac{2}{3} x^{3/2} + C \). In real-world applications, this integral could be used to calculate the area under a curve representing the relationship between distance and time in physics. If you're plotting distance over time in a graphical representation of free-falling objects, integrating the function gives you the total distance traveled over a specific interval. It's an essential tool for engineers and scientists when dealing with motion derived from acceleration.
