The connections and visuals are stunning.
I am a simple soul like that.
Currently doing advanced high school math in order to fix my fundamentals.
Fundamental weaknesses that I discovered:
- I hated trig and was bad at it
- I didn’t understand certain algebraic manipulations
- Integrals, I still need to learn how to do them
That’s what I am fixing with my high school advanced math course. And it’s working!
But the explanations kinda sucked, especially trig explanations.
They did stuff like:
sin(2a) = 2sin(a)cos(a)
With no explanation why!
Just suck it up and memorize.
In high school I refused this treatment and got told off which is how I started to dislike math.
Now I am older.
I am wiser.
I still refuse :P
I still get told off (in the course I am doing now).
But I know it’s not their fault, I’ve simply learned that most math teachers can’t help me as they are not in the business of teaching the why. They teach the how (which I need as well, I need both the why and the how).
Enter 3Blue1Brown
He taught me:
To feel why 1/x is the derivative of ln(x). Yea, I can derive it, but now I feel it.
To feel why the midpoint plus/minus a deviation is a way of expressing the quadratic formula.
To feel why double angle identities are the way they are (he shows it visually with complex numbers, it’s so obvious! How can I forget something that I can visualize in my mind as easy as visualizing my dreams?).
To feel why sin(pi/4) = sqrt(2)/2
Khan Academy did it for a few other sin(...) values.
Suddenly, this high school math course transformed from not understandable to super duper obvious!
3Blue1Brown shows the why visually
The course shows the how.
I need both.
But there are a lot of courses of similar quality, but there is only one 3Blue1Brown.
(There are others like Khan Academy, Numberphile, etc. but 3B1B has shown me the beauty of math, not just the context. Animations with piano music really help!)
