How to Find the Arc Length of Curve y = x^3/3 + 1/(4x) from x = 1 to x = 2 | Glass of Numbers

In this video, we are finding the arc length of a curve y = x^3/3 + 1/(4x) from x = 1 to x = 2. It's a typical arc length problem that only requires the work of plug-in to the formula and solve. However, there is a tricky step when it comes to the integration: We will need to recognize that the expression in the square root is a perfect square!
