Hey everyone! Math PhD student here! I have an Etsy page where I sell calculus and algebra notes, cheat sheets, and study guides. This is my most recent listing, to help with algebra 1!

GUESS WHO'S BACK

Exams are just around the corner, and I have recovered (mostly) so got back to productivity. I missed my notes <3

The 1989tv vault tracks are stuck in my headddddd my favourite is Now that we don't talk. If you are a swiftie, what is your favourite vault track?

Things I did today:

40 out of 55 slides of a PPT

19 out of 27 concepts from Module 1 of computer science

Ate biryani :3 (and then had a tummy ache LOL)

P.S. the whiteboard is @studaxy's I STOLE IT (jk, they gave it to me lol)

🎧 Suburban Legends — Taylor Swift

Jacobson's Basic algebra 1 gives such a nice argument for why algebraic numbers have minimum polymials, making it a corollary of the fact that polynomial rings over fields are principal ideal domains. Consider a field extension E/F (i.e. a field E that contains a field F). For any u ∈ E we have in E the subring F[u] and the subfield F(u). These are defined as the smallest subring and subfield of E respectively that contain both F and u. If E = F(u) for some u ∈ E, then E/F is called a simple field extension.

Let F(u)/F be an arbitrary simple field extension. Consider the polynomial ring F[X]. By the universal property of polynomial rings (which is essentially what one means when they say that X is an indeterminate), there is a unique ring homomorphism F[X] -> F(u) that sends any a ∈ F to itself and that sends X to u (you can think of this homomorphism as evaluation of a polynomial at u). If the kernel of this homomorphism is the zero ideal, then F[u] is isomorphic to F[X], so u is transcendental over F. If the kernel is non-zero, then by definition there are non-zero polynomials p ∈ F[X] such that p(u) = 0 in F(u), so u is algebraic over F. Because F[X] is a principal ideal domain, there is a polynomial p that generates the kernel. In other words, p divides all polynomials q such that q(u) = 0 in F(u). Two polynomials (over a field) generate the same ideal if and only if they differ by a constant factor, so there is a unique monic minimum polynomial in F[X] for u.

#math #it also follows immediately that if u is algebraic then F(u) = F[u] #because the image of F[X] under the homomorphism is an integral domain it must be that the kernel is a prime ideal #so bc F[X] is a principal ideal domain it follows that it is a maximal ideal #hence its image F[u] is a field #another note: this works even if u is an element of F #that is exactly the case that the minimum polynomial is linear

12.21.23~ Finished topic 1.2 for linear algebra, and have about 3 more problems to do for the practice section. Some of what I learned today: 1. A coefficient matrix includes only variables and their coefficients, but an augmented matrix includes the values to the system as well + 2. A basic variable is associate with a pivot, all other variables are free + 3. In a system where variables are free, there are infinite solutions + 4. Row reduce from left to right and find pivots in REF (row echelon form) + 5. RREF (row reduced echelon form) is used to solve a linear system in its entirety, especially if free variables are a concern + 6. Inconsistent: 0 solutions / Consistent: at least 1 solution / Consistent and unique: 1 solution

I also made chai with milk for the first time (my mom usually uses water) and it was nice; next time I'll ratio it to 2/3 water 1/3 milk instead of the opposite

Mathematical Methods

Mathematical Methods is a Maths course in Australia commonly taken in the last two years of secondary school.

It is the equivalent to taking AP Calculus AB in America. In the UK, A-Levels Mathematics (*) goes a little more in depth than Methods.

Here are a few techniques that should help gain one’s understanding in Methods.

Algebraic methods

How to *not* use long division

Understanding quadratics

The quadratic formula

//

Addendum: 10 March 2024

*Math Methods should be equivalent to Edexcel A-Level Pure Maths (no proofs, sequences and series, parametric equations, modulus, and reciprocal trig) and Statistics 3.

My new fancy Etsy link! https://leahcmath.etsy.com

Hi! I'm Leah, a second year math PhD student. On my Etsy I have study guides for Calc 1 (same class as AP calc AB) and Algebra 1 (same class as college algebra) as well as a full note set for Calc 1 (using James Stewart, so perfectly in line with the AP curriculum). I am also working on a full set of notes for Algebra 1, but I haven't finished that yet.

I also sell sheet music for some of my compositions, though it's mainly the math notes I'm advertising here.

Etsy tells me if you use this link instead of the links I posted before, good things will happen. I think the good things happen to me, not you, but you still get cheap math notes and that's still good! Plus a tip, if you fave an item of mine or leave it in your cart, Etsy will email you like a week later with a discount.

Anyway, use this link instead of the ones I posted previously! :)

This user was in hyper productive mode today

Am feeling so satisfied and happy that i have completed some task today like for me this is a super hyper productive mode after a very long time ..😅

Task completed

linear Algebra 5.1,5.3,3.3

Probability regression,law of addition , conditional probability ,solved some exercise question

Mobile computing week6 ,week8

Ps: My first final is of Mc but i am taking it slowly becoz i know all the stuff and the theory slides contain like nothing as i know everything from code prespective so i will just go through slides and just read them the main reason is that it has only 2 credit hours and my prof give equal grades to everyone so for like wasting time its better that i will go through the subject which has 3 credit hours so for now i need to go through linear algebra ,prob and db.....

Ok, time to try this!

50 notes and I work harder to study Arabic

100 notes and I start reaching out to people more

150 notes and I make an Undertale Au

200 notes and I make a blog for that Au

250 notes I learn algebra and don’t just rely on mental math

I plan on doing most of these anyways but extra motivation is always awesome!
