Sum of squares and cubes, using difference calculus.

[Click here for a PDF version of this post] Motivation. I showed Karl Gauss’s trick for summing a \( 1, 2, \cdots, n \) sequence. Add it up twice, reversing the sum and adding by columns \begin{equation}\label{eqn:sumOfSquares:21} \begin{array}{c|c|c|c|c} 1 & 2 & \cdots & n-1 & n \\ n & n-1 & \cdots & 2 & 1 \end{array} \end{equation} We get \( n + 1 \), \( n \) times,…

dear sports bra companies if you want to make your bras with small/medium/large/etc sizing that doesnt account for differences in band and cup size using sister-size logic FINE i cant stop you but STOP LYING. "28c, 30b, 30c, 32a, 32b = small" Okay. i believe you i guess. but you Cannot just Keep doing that without actually using ur Brain. there is no World where 28g and 36c are the same size are you fucking stupid You can't just keep adding band inches and subtracting cup inches Nothing fucking works like that You can't sister-size forever I hate yuo i hate you i hate you i hate you i hate you

#text #Bra shopping makes me want to [violent threat here]#also i have no idea what my bra size actually Is bc i've gotten between 28g and 32dd on the abrathatfits calculator depending on the day #and thats complicated by The Rib Injury + probably needing to size up the band #and also the fact that different companies vary on whether like. a size 30 band #is for 29.5-31.5inch rib sizes #or for 27.5-29.5 inch rib sizes. bc i've seen some with 'add 2' and some without #but they dont all specify!!!#IT SHOULD NOT BE THIS HARD. this is why i have such a big part of my brain convinced i could jus tmake my own #Like it cant be harder than learning freeking calculus. God #Also this would all be so much less difficult if i would just swallow my pride and go try stuff on in person. but im not doingb that

You cannot save it.

#(no hate to anyone whatsoever)#(but i feel like people are forgeting that youre supposed to put your /faves/ in the blender)#(blender hell and real hell are very different)#your fave is being blended #you cannot save them #blend requests #calculus #math #mathematics

IM SO CONFUSED.

#boycritter et al #ap credit cant be used to satisfy gen ed requirements OR division requirements #so like??? what can it be used for???#it seems like it mostly lets you take more advanced classes right away instead of the intro classes?#bc i can get up to 8 classes worth of credits from my ap scores #but seemingly it doesnt get satisfy any of the degree requirements???#and like. i need xxx credits to graduate. and i can get xx of those from ap tests. allegedly. but i still need to take a full course load??#wait. division requirements are a different thing from major requirements. i think.#but still.#guys im so confused. can colleges make things easy.#also on some parts of their website they say ap scores can be used for gen ed requirements and on other parts they say otherwise #guys if i took 12 ap classes and all thats good for is getting me out of INTRO TO CALCULUS im going to be so pissed actually

me adding "it builds the economy" to every answer in business class (I have no fucking clue what it means to build the economy)

#business #School #Business memes #But fr what the fuck does it mean to build the economy #Mf it's not a house???? You don't build that shit????#I'm so good at business #Don't come at me for calling it business y'all I'm still in a year where everything sciency and businessy is grouped together into 2 subs #Dunno if imma do accounting or marketing or whatever yet 💔#Hey if y'all Americans can split math into like ninety different flavors we can do the same with science and business #Why are there so many flavors of math in America???#The fuck is calculus????

another operator roleswap. did not intend for this to also be between a brooding guy and a nice girl like with Myrtle and Vigil, it just kind of happened.

#did this half because flamebringer and perfumer are a fun duo to think about (gardeners with very different demeanors)#and half because i think the idea of murderer perfumer is funny #arknights #arknights perfumer #arknights flamebringer #luc art #now off to do my calculus homework

Speaking as an astronomer with an interest in science history:

#1 Isaac Newton was just LIKE THAT

#2 Isaac Newton and Edmond Halley (Maxwell Raynor) were very close friends so that has some potential implications.

#also I had a science history professor back in undergrad who told some absolutely unhinged stories about these two #I do not have sources so he could have been making shit up #but according to him Newton got his boyfriend to send anon hate mail to Leibniz over the whole calculus thing #and Halley had separate affairs with both a ship captain and his wife and then had to take a different boat back to England #again don’t quote me on any of this I haven’t talked to this professor in like 5 years #the magnus protocol #the magnus archives

I thought you liked physics ?

yes I do. I love physics. I love it bc I was raised by a brainiac engineer mother who taught me to see math as fun from a very young age. and sometimes it pisses me off bc I don’t understand concepts immediately and my ego is HURT but then I humble myself and learn it and I’m back to adoring it again

#I did an independent study in a biophysics lab for a semester which was cool #I do orgo research now but I think so much of being a good researcher is integrating methods from different disciplines #and this will probably apply for when I’m a doctor too #I was never an ‘ewww I hate MATH’ person like I literally took advanced physics & calculus classes willingly bc it was so fun #which is why I was so mad when the whole girl math trend happened. what is girl math. what do you mean #I just despise the trend of girls being corralled into less math based fields bc of this. I am never buying into that narrative ever #ask
