Learn how to evaluate the integral of a constant

The video tutorial explains the concept of a definite integral, focusing on calculating the area under a curve. It begins with an introduction to the integral's components, followed by a graphical representation of the function F(x) = 4. The tutorial then demonstrates how to calculate the area of a rectangle formed by the function's graph, using the formula for area. The definite integral is determined to have a value of eight. The session concludes with an invitation for questions.

What shape is formed under the curve between the given bounds?

What is the value of the definite integral calculated in the text?
