This lesson discusses the concept of a cross product of 2 vectors in 3-Space and shows how to calculate the cross product with vectors in component form. Some properties of the cross product are also discussed along with an example involving the magnitude of the cross product. This lesson was created for the Calculus and Vectors (MCV4U) course in the province of Ontario, Canada.
Amazing, Life Changing Tutor
Before I met Jonathan, I was struggling through most of my STEM classes because I was simply not studying properly. He taught me all kinds of new study habits that would help me to save time, raise my grades, and lower my stress. Jonathan was specifically tutoring me in vector calculus and is an amazing tutor on the subject. You will walk away from a lesson with a game plan knowing exactly what you need to do before your next session with him or before your next exam in order to do well in the course. I highly recommend him as a tutor.
In this example, we are given a ratio and then asked to apply that ratio to solve a problem. No problem!
