Y’ever read something and have understanding that has eluded you interminably suddenly stop, curl up, and snuggle neatly into a fold in your brain because a new way opened to it?

kinda hypocritical of me to teach integral calculus when i haven’t done a single integral since i discovered https://www.integral-calculator.com in my last year of high school.

Trigonometry Integrals
∫ sin u du = -cos u + C
∫ cos u du = sin u + C
∫ tan u du = -ln |cos u| + C
∫ cot u du = ln |sin u| + C
∫ sec u du = ln |sec u + tan u| + C
∫ csc u du = -ln |csc u + cot u| + C
∫ sec^2 u du = tan u + C
∫ csc^2 u du = -cot u + C
∫ sec u tan u du = sec u + C
∫ csc u cot u du = -csc u + C

I just realized that there's an amazing book on calculus which people can use to learn it. Some have probably heard it from the YT channel Mathologer. It's out there on the web, for FREE.
Here it is:
How good is this book? Well, check this out:
(idk if the image is blurry though... but you get the point.)
Happy calculus!

I’m such a whore for calculus like if you told me three years ago I’d be moving ahead to the harder integral problems bc i was bored i would call 911 on you

Anyone who solves this and also gives the solution (or even just the final answer) will get a virtual cookie <3

i have since realised that there are so many things wrong with this that i'm going to turn it into a challenge to find all the wrong things
hint - start with cauchy's integral formula for W(x)/x

Replacing physical buttons and controls with touchscreens also means removing accessibility features. Physical buttons can be textured or have Braille and can be located by touch and don't need to be pressed with a bare finger. Touchscreens usually require precise taps and hand-eye coordination for the same task.
Many point-of-sale machines now are essentially just a smartphone with a card reader attached and the interface. The control layout can change at a moment's notice and there are no physical boundaries between buttons. With a keypad-style machine, the buttons are always in the same place and can be located by touch, especially since the middle button has a raised ridge on it.
Buttons can also be located by touch without activating them, which enables a "locate then press" style of interaction which is not possible on touchscreens, where even light touches will register as presses and the buttons must be located visually rather than by touch.
When elevator or door controls are replaced by touch screens, will existing accessibility features be preserved, or will some people no longer be able to use those controls?
Who is allowed to control the physical world, and who is making that decision?
