    God that magnetic ruler on the board is such a good invention. Why don’t I have that at my school? Teachers won’t be able to draw straight lines when they are holding a huge ruler with two hands.

      I don't think it is an appropriate use of the term "canon fodder". What he seems to be saying is that understanding what he has just written is central to understanding the definitions of the trigonometric ratios which are to come shortly.

    sir, can u pls tell me how I can create passion for math? Whenever I see math, I get scared. my friends always say that math is so easy & it's full of fun but don't know why I don't get any fun in maths. besides, I always try to avoid maths & don't practice a lot. so I always get poor marks. but I want to get good marks and want to create more n more passion for math. pls give me some advises. It should be mentioned that, I love physics a lot. my friends always says to me that if I can love physics then I also should love maths. but I don't get any interest in maths. so pls pls pls give me some advises.

    • @Metalhammer1993
      @Metalhammer1993 7 лет назад +6

      first thing is, forget about the marks. i hated maths because it only PROVED BY MARK i´m stupid. cause here in germany math marks are intelligence tests or at least treated as that. Maths was a lying monster telling everyone i am stupid. i´m to dumb to think logically. that´s what my maths mark told everybody. and that was part ofd the reason i hated maths. first of. there was no logic in maths and i often still don´t see it. it´s just i do what i learned to do and get a result. no logic or even thought build into it. and that´s why i hated maths.
      forget your marks for that moment. as long as you look at them and you´re frustrated because you can´t get jack shit done. you´ll hate it. it´s the reason i hated it with a passion. i left lessons with headache sometimes because i missed so much. and i had zero motivation to even try to get better. cause. getting better at getting headache means logically getting more headaches doesn´t it?
      what i noticed someday was there were a few things i´m good at. differentiation cheap stuff. easy peasy. okay don´t tell me to do a derivative of the riemann zteta function i´d die trying, but basic differentiation takes me for most functions about three seconds. but i noticed i had no clue WHY the rules i memorised and used like they are second nature worked. so i tried to find different proofs for them. first other guys proving them than replicating them. and bit by bit i got more interested in even crazier maths. like the Riemann zeta function. this thing is insane. And given i´ll never need it it´s fine if i don´t get it. i can just say thumbs up to the guy explaining all that to me, he clearly knows what he´s doing and that´s cool. So first try watching maths videos on youtube with more a soccer match mentality. next step is, maths is a match you cannot only watch but also take part in whenever you want.
      so first search on youtube for stuff you´re ghood at. and look where it goes. like watch how great of a tool linear equations are.as a chemist i can teach you a billion tricks to get things to turn into a linear equation or at least a linear graph. cause linear functions are fucking great. they mean i can draw stuff. and trust me if i can get a linear function i can draw i´m faster and more precise than many computers just with eyes and a ruler. and that is crazy right? like ever seen how police tests whether you were to drunk to drive or not? thatßs a linear equation they make. they take a blood sample of you ut it in a machine and get a signal. than they take a blood sample and add alcohol to it, put it in the machine and get another signal. than they add more alcohol to another sample and put it in the machine and get a third signal. from these signals they draw a line and where that line hits te x-axis meaning the zero signal line they calculate how much alcohol was in your blood. simple graphic method but pretty dang precise. so take something simple and see what you can do with it. that´s where the fun in maths comes from for me

      +Metalhammer1993 Thank you very much for such a beautiful explanation. I'll surely try to search fun in maths by starting with simple things.

    • @Metalhammer1993
      @Metalhammer1993 7 лет назад +1

      you´re welcome. Always start at the simple things. if you wanted to learn piano you wouldn´t start with Bachs toccata and Fugue in d-minor either wouldn´t you? you could start there but you´d only learn to hate the piano because it seems impossible. in maths or in school in general you often face that you have to start at things way beyond your understanding because there is no time to start at the general idea or there is no time to get from the general idea to the technique and you´re forced to learn two seemingly entirely different things without any connection between them.
      i saw that with a tutoring student today. Getting her to give me a formula for the slope of a line was impossible because she did not understand how the trick with the triangles worked. (you know making a triangle and getting the slope from dividing the b side over the a side) she did it all the time but she did not see that she always was measuring difference on the y-axis and divide it by difference on the x-axis. why? she never thought about what she did. she just rolled with it. She had no time tzo think about it. If i had just given her the formular she might have gotten it totally wrong. so i had to slowly work my way from that triangle to the slope formular. took half an hour but it´s worth it.

      i can relate to you!! the thing is- practice isnt the key to math, interest is. and ive always been interested in math, but incapable of it (according to my grades).
      but ive been finding math so much more fun than what they teach at school because well, they dont teach you math in school for anything but good grades.
      if you want to get passionate about math, i recommend watching math in action. as in, dig in deeper. there are so many channels out there that really use what we learn in school and bring out such interesting and different concepts [VSAUCE, watch college lectures on math, Eddie Woo himself, numberphile, etc] also, I recommend buying math books that dont relate to school books. maybe of the same level, but books that dive into the fundamentals- not just throw 50questions at you and have you memorise a formula to solve them. and stop thinking of it as an alien subject!! schools do more than just convince you that u need to be "hardwired" for math to be good at it, but that's just straight up not true. math is literally a form of art. it's a language of it's own, and we're born with the basics already. the grammar is what we're to learn. haven't you ever thought how much more easier numbers are? like they just *make sense* . you can say you like chocolate but that's very vague. when you say you like it about 7/10, it just. makes sense.
      numbers are easy, and developing a passion for it will change ur life for the better. only thing- stay strong, rather *immune* to schools telling you you're only worth your grades. schools never teach you the most important things in life anyway.

      +Netra Mittal thank you so much for such a good advice. I'll surely try to find passion in math. yeah, its true that we normally run after good grades but math is such a sensitive subject. if we can't understand all the main things properly we can't do math correctly. I just hate maths cuz I don't get good grades besides, my friends tell me that math is full of fun & it's very easy but I'm still unable to get good grades.
