Use the area of triangles to represent the integral

The video tutorial explains how to evaluate an integral using the area under a graph. It begins by analyzing a line graph, identifying its intercepts, and then visualizing the integral as a net area. The tutorial emphasizes using geometric shapes, such as triangles and rectangles, to calculate the area. The process involves understanding the signs of the areas and performing calculations to find the net result. The tutorial concludes with a final area calculation, ensuring a comprehensive understanding of the integral evaluation process.
