Estimating Gradients and Area Under a Curve

The video tutorial covers estimating gradients and calculating the area under a curve. It begins by discussing the limitations of using average gradients and suggests breaking graphs into smaller zones for better analysis. The tutorial then explains how to calculate exact gradients using tangents and highlights the challenges of estimating these values. Finally, it covers the concept of calculating the area under a curve using trapeziums and triangles, emphasizing the importance of equal widths for accurate distance estimation.
