My Lecture made 30 min presentation on this section using his 34 page document, while presenting he wasn't explaining anything but just saying you need to read this and that........ and his notes were so confusing he is a joke, and before I found your videos I even told my self that I won't answer this section in an exam but now I understand it completely thank you so much , you're a life saver.

for 33:26, we can also say that H is not a subspace of P3 because it encloses polynomials that belong to P2 or P1?

@goldeneyes581 Жыл бұрын

No, we can’t because It’s the sub space of polynomials 3 or less that we are checking for (whenever you look for polynomial n, it’s polynomial n or less)

@haneulkim4902 2 жыл бұрын

@gamerspakistan5507 Жыл бұрын

sir in the above example of a subspace where f(4)= -2 ; why not can we consider f(x)=(x^1/2) - 4 ????? . It can also give us a zero vector and also -2?

@jordanwebster3272 Жыл бұрын

The "vectors" in this set are the functions. The zero function must be f(x)=0 in the vector space of all functions using normal addition and scalar multiplication. The set of functions such that f(4)=-2 does not contain f(x)=0 so it is not a subspace. f(x)=x^(1/2)-4 is in the set but not the ZERO function. You can also show that if two functions f and g are in the set, their sum f+g is not in the set. (f+g)(4) = f(4)+g(4)= -2+-2 = -4 so the sum of two functions in the set is not in the set. Therefore it is not a subspace. A good exercise is to show scalar multiplication does not work either.

I think there was a mistake with the polynomial vector subspace example the polynomial to check was from P3 not P2 I think that eventually got lost anyway who cares.
