[WIP] Cheatsheets for CM1015 Computational Mathematics

[lamafab]

NOTE: This is Work-In-Progress, do not merge yet

Hello

I'm currently working on a collection of cheatsheets, meant to be useful for studying. Preview:

• Number bases
• Sequences and Series
• Modular Arithmetic
• Trigonometry
• Graphs of Functions & Kinematics
• Trigonometrical Functions & Identities
• Exponential & Logarithm Functions
• Gradients of Curves & Differentiation
• Vectors
• Matrices

Do note that those are currently and actively being worked on and might contain mistakes or be incomplete. I will go over everything again and - assuming you're interested in merging this - will ping you when I think it's ready, probably around the mid-terms. Any feedback/criticism is welcome. More topics are coming in the future, the goal is to cover all relevant topics of that module.

Hey Fabio, just a suggestion.

Regarding Graphs of Functions & Kinematics, specifically the Kinematics section:

I found really handy to think in terms of derivatives and integrals. So, rather than remembering all the formulas, you can start from the Fundamental law of Dynamics F=ma to deduce the position law:

a -> integral over time -> v -> integral over time -> r

a = constant in your case

v = ∫a dt = at + vo

r = ∫v dt = 1/2 at^2 + vot + ro

The vice versa is also valid:

r -> derivative with respect of time -> v -> derivative with respect of time -> a
