AI Thread Summary
The discussion centers on seeking beginner-friendly resources for understanding trigonometry, as the user expresses a dislike for the subject but recognizes its usefulness. They desire materials that explain basic concepts clearly rather than just memorizing formulas, specifically mentioning interest in the role of pi in converting degrees to radians. Recommendations for books or recorded courses that simplify trigonometry are requested. The user aims to overcome their fear of the subject to feel more comfortable with future math studies. Overall, the focus is on finding accessible learning tools for foundational trigonometry.

First of all, sorry if I posted in the wrong category (it happened with the last topic I made, all this names are confusing :D ).

I made this topic because I don't know trigonometry. Just a few notions (like the formula of sin,cos,tan). But I also hate it a lot.
And because learning is basically the thing you do when you learn stuff you didn't know, my trigo-phobia makes me really want to try to understand it (that and the fact that it is super useful).
I don't want to be great at it, I only want to understand the basic concepts (and to find out what is pi doing in the formula for converting degrees into radians :D). I mean, I really want to understand it, not just memorize formulas.
So can you guys help with some kindergarten(ish) trigonometry learning material?Anything from a book to some recorded courses would to the thing, I just want them explained the best way they can be, so that (hopefully) I don't get goose-bumps every time I open a Calculus book :D

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Thread 'Imaginary Pythagorus'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
