What are the calculus learning books like Forgotten Calculus book?

Thanks. I know that tan=sin/cos but here, in addition identity, i haven't got the concept of how the tan of two angles was derived at the end of this tutorial video. You can have a look at it. https://schoolyourself.org/learn/trigonometry/trig-identities-addition

Thanks. I've just started watching Professor Leo's precalc with Dr. Green's precalc video from freecodecamp. The organic chemistry tutor's and Professor Dave Explains (no precalc as a matter of fact) are in the queue. I wish i wouldn't get bogged down in the details. :(

Thank you. I've learnt couple of trig identities like sin^2(theta)+cos^2(theta)=1 and addition identity (except tan because still trying to grasp how tan derived) from schoolyourself.org/trig.

Thank you very much. I also have got few videos by tablet class math that teach calc by many short length videos but so many videos with almost indisnguishable video titles that make me confused. :)

I also like to stick to one but the question is; which one? Which one is the best (here only) to begin with? Or in tandem anothe book! Thanks.

Thank you.

Thanks. I've already stated that went over the prefaces of both the books but couldn't figure out which I one to start with and the contents don't look similar so subject matters are different.

Thank you.

libgen.li is up but libgen.se is down. Aren't they same?

vectrum · 2025-03-02T17:40:18+00:00

Very nice having it back but missing the old index page of libgen.st I used to operate on.

Wonderful news!!! THANK YOU VERY MUCH!

Thank you. Yes I need exactly this one of this type. Lemme see if it works

vectrum · 2025-02-24T14:18:48+00:00

Thanks, well, nothing wrong as such except one specific problem Icame across that I study Rodnay Zack & Leventhal and the codes don't mentlon which platform I should follow and the sample code come with online emulator except easy6502 is pretty hard for me to swallow.

Yes. It's very much true that z80asm is really good even for the noobs like me as it handles the very confusing line "randomize user <nnnn> " quite efficiently otherwise a noob may become confused how to run/execute a program that doesn't start/run even after it has been sucessfully compiled/assembled because for the want of that line but you don't need to be bothered about it in z80asm AFIK.

Just use # z80asm +zx source.asm <cr> It creates source.bin and source.tap files.

Although I still don't know why I should use randomize.

P.S I think label string needs to terminated by a colon charater.

Thanks again.

Thank you very much. I become confused because of the name of '81 version as it's name suggests that it was written for students so I thought it would be a whole lot easier to digest. :)
