The video tutorial explores the geometrical applications of calculus, emphasizing its role as the core of mathematics courses. It distinguishes between pure and applied mathematics, highlighting the practical use of calculus in solving real-world problems. The tutorial introduces four key geometric ideas: increasing/decreasing functions, stationary/turning points, monotonic functions, and concavity. It also covers the concepts of maxima and minima, and their applications in curve sketching and optimization. The tutorial aims to provide a comprehensive understanding of how calculus can be applied to analyze and solve mathematical problems.

What is the main focus of geometrical applications of calculus?

• Calculating probabilities
