The video tutorial covers the extension of 2D vectors into 3D vectors, focusing on vector notation, operations, and calculations. It begins with a review of 2D vector representation and transitions into 3D vectors, explaining how to perform arithmetic operations like addition, subtraction, and scalar multiplication. The tutorial then delves into calculating angles between vectors and axes, emphasizing the importance of understanding planes and angle positioning in 3D space. The session includes practical examples and encourages students to visualize and solve problems using different perspectives.
