  • congrats. I have only completed a bachelors and it was hard. I literally spent blood and tears (and tons of sweat). And my guess is that you had to go through something similar (maybe not the blood part, i hope not the blood part). That shows that you have are committed and dedicated. Sorry I could not be with you for your convocation, and I do not deserve to be forgiven. I only wish you success and happiness in your life. What I have learnt in my life is - hard work pays off. I am not relegious, and will not go in to “god works in mysterious ways” kinda shit, but what i have learned is that if you make honest efforts, you can achieve stuff. If you failed, then do not be upset about it. It is natural to be upset, but to try again and succeed is even more satisfying. Best of luck for rest of your life. I’m proud of you and what you have achieved.3




  • if i am not wrong, there is only one problem - sum to x (x times)

    when we write it in a bit more concise but equivalent notation - d/dx sum_1^x x it basically becomes x^2 again. It is kinda a a=a proof, so not very interesting but that is the only problem. since sum is happening a variable number of times, we can not really let it loose.

    in a more reasonable wording - what the image showed was interchanging differentiation and sum (like instead of doing sum after diff, instead of before), and such operations are allowed, but if the sum and diff are independent (not based on same variables).

    this interchange works if you used some other variable which is independent of x
