Use the information in the image below to determine magnitude and direction for the vector product of vectors M and N.

Given î, ĵ and k̂ represent unit vectors along the +x, +y, and +z axes respectively. Determine the cross products of the following: ĵ × î, k̂ × î, and k̂ × ĵ.

If vector $P$ = 5.2î - 2.9ĵ + 1.8k̂ and vector $Q$ = 6.7î + 3.4ĵ - 2.1k̂. Find i) their cross-product, ii) the angle between the two vectors.
