Problem 1.2.2 From Gilbert Strang's Introduction to Linear Algebra fourth edition. Chapter 1 - introduction to vectors - length and dot products.
Enjoy, and I am available for tutoring and private classes! :)

Calculate the dot products u⋅v and u⋅w and u⋅(v+w) and w⋅v :
u=(-0.6,0.8) v=(3,4) w=(8,6)
Compute the lengths ∥u∥ and ∥v∥ and ∥w∥ of those vectors. Check the Schwarz inequalities |u⋅v|≤∥u∥∥v∥ and |v⋅w|≤∥v∥∥w∥.

Hello Sofia, thanks for the videos. They are really helpful. Are you planning to continue this series? I wanted to understand 1.2.6 c. How is it a line ?
