Whether you love or hate math, this series of videos about calculus is amazing. Throughout most of our education, we are taught how math works and what to do, but never really why. These videos add depth to calculus and I feel so enlightened after watching them. I think getting an understanding of why something works is extremely important in order to understand what to do from there. I HIGHLY recommend this series!! If you don’t have time for it, just watch the first one :)
HL Math is a Hell of a Subject but damn if I'm not proud of my notes follow for more calculus aesthetic
HL MATH : started hw for my options!
HL MATH: started studying for my math exam which is in 2 weeks ahh!!!!
Here’s what you need to know for CORE 1
1.1 Arithmetic sequences and series; sum of finite arithmetic series; geometric sequences and series; sum of finite and infinite geometric series. Sigma notation. Applications.
1.2 Exponents and logarithms. Laws of exponents; laws of logarithms. Change of base.
1.3 Counting principles, including permutations and combinations. The binomial theorem: expansion of (a+b)^n, n E R.
1.4 Proof by mathematical induction.
1.5 Complex numbers: the number i=√-1 ; the terms real part, imaginary part, conjugate, modulus and argument. Cartesian form z=a+ib . Sums, products and quotients of complex numbers.
1.6 Modulus–argument (polar) form z= r(cosx + isinx) = rcisx = re^(ix) . The complex plane.
1.7 Powers of complex numbers: de Moivre’s theorem. nth roots of a complex number.
1.8 Conjugate roots of polynomial equations with real coefficients.
1.9 Solutions of systems of linear equations (a maximum of three equations in three unknowns), including cases where there is a unique solution, an infinity of solutions or no solution.

Day 8: Been doing math all day and I’m tired of doing proofs, but I guess practice makes perfect!
This is one of the main differences between HL and SL, you’re expected to be able to prove almost everything you learn in HL so keeping a notebook or worksheets with your proofs is always helpful. I group mine based on topics (Core 6), and so this is in the statistics and probability one!
HL Math Day 2: I have a math test tomorrow for statistics and probability and just got done my cheat sheet and practiced some proofs.
The most important part when it comes to data is to know all the ways you can go about when solving a question, unlike the other core topics within the course.
For example using a graph, a sample space, a tree diagram, or permutations and combinations.
Pay attention to the hints they give you too. Some questions will state how the probability of X and Y are ø to check that you understand the difference between independent vs. mutually exclusive events and their laws.
Practice, practice, practice.
I deserve at least a pity point for honesty
