Lesson: Cross Product in 3D Mathematics • Third Year of Secondary School

Students will be able to

• define the cross product of two vectors as the product of the magnitudes multiplied by the sine of the angle between the vectors,
• calculate the cross product of two vectors in space using their components (i.e., a determinant),
• understand the properties of the cross product in 3D,
• use the geometric meaning of cross product to solve problems, in particular, finding lengths or areas.
