How to use Cardinal Directions with Vectors

The video tutorial covers the use of cardinal directions with vectors, focusing on understanding angles and directional terms. It begins with an introduction to cardinal directions and addresses common challenges like directional impairment. The instructor provides tips for overcoming these challenges, such as drawing a compass rose and keeping paper oriented vertically. The tutorial explains how to identify angles using cardinal directions and introduces the concept of complementary angles. It concludes with a review of specific directions and emphasizes the importance of understanding cardinal directions in vector analysis.

What was the resultant velocity vector in the previous lesson?

• 60 millimeters per second at 30 degrees West of South

• 70 millimeters per second at 45 degrees North of East
