Скачать или смотреть Cross Product of 2 Vectors (How to Find)

Learn how to find the cross product of two vectors with this step-by-step tutorial! Mario's Math Tutoring guides you through two examples, demonstrating the determinant method using standard unit vectors (i, j, k). Understand the right-hand rule to visualize the direction of the resulting vector, and learn how to verify that the cross product is orthogonal (perpendicular) to both original vectors using the dot product.

In this video, you'll discover:
