CONTENT: EXERCISE 1: Show that R^n is a vector subspace. in time (0:35) What is R^n? in time (1:02) To be a vector subspace, 3 tests are necessary: o E S u + v E S α u E S where α E R in time (4:22) Answer to exercise 1 in time (8:31) EXERCISE 2: Check if the given subset is a subspace. in time (8:40) EXERCISE 3: Curiosity: Is the null vector a vector subspace? in time (10:46) What is a null vector? (11:01) Examples. A vector is any element of a vector subspace. in time (11:27) Check the answer to exercise 3 in time (14:04)
