>Learning math (easy math)
>Try to understand what makes some funcions non-linear (like for (x+Δx)^2, if you view it geometrically you have a perfect square and you have to account for Δx twice because both base and height and changing, the total change is 2xΔx + Δx^2 but when Δx tends to 0 only its derivative 2x remains, you can also write x^2 = x * x , see that Δx needs to be accounted for twice and think something sus is happening compared to linear multiplication)
>Noticed 1/x isn't linear and asked why in a discord server with frens
>No one knows why
>Came up with an analogy similar to the square but no one seems to get it
>Someone there who is supposed to know a lot more math than me treats me like a fucking retard with questions like "Do you know what a slope is"? "What is the derivative at this point on the graph"?
>We make no progress after hours discussing and it's been imposible to explain that derivatives are related to the algorithm of the function itself
Never felt so fucking frustrated. I can't talk about math with any acquaintances because this happens. I can't talk about math here because i'm still like a toddler for this general. I don't actually study math I just ask questions for no reason but this is not working.
I should get my shit together and read books, I'll try again /mg/.
