What is the best way to memorize math formulas?
Its very simple for everyone.1.Learn basic laws of mathematics.I think you are familiar with associative law,distributive law,Commutative law etc.2.Learn and correlate with real life.3.Make short notes of formula in creative way.You may use *& short symbols and also according to your own way.4.Understand the formula.Take a simple example:-You will prove in different way.With the help of Geometry approachAlgebraic method5.Use different channel to learn the formula.6.Practice more important.7.Stay healthy8.Revise daily before sleeping and after sleeping .10–15 minutes enough for memorizing.9.Go Smarter and productive.∆In childhood∆Crazy clock∆Fun with calculus formula in smart way∆Rainbow math sticks∆Romance with mathFresh your mood with old joke it may be sarcastic ;)Girl:How do I look ?Boy:Tanc /SincGirl:What?Boy:Tanc/Sinc=(Sinc/cosc)/sinc=1/cosc=Secc ;)∆Love Series(Pyar unlimited)∆Something funnyHappy Learning!Chouhan Gajendra

I am very weak in maths. How can I develop it?
I'm very weak in Maths, or I don't know whether it's something that I, myself developed over the years. From my 7th grade, I started loosing interest in Maths since my teacher wasn't that good and she only appreciated students who did well and insulted us very badly. From that year, I just gave up my hopes on Maths and considered it as a shitty subject and pretended like I didn't care when I was really really very sad on getting very low marks in Maths when I was an excellent student in the class and scored more than 91% in other subjects, Maths always bought me down when it came to ranks. I was so depressed, I started hating Maths, and it became a nightmare for me. The day before the exam, all I remember doing was crying, crying and crying. I couldn't bear the tension it gave me. It still does. I suffer from anxiety even though I'm young; and no one is allowed to put so much pressure on me because it's trouble. Whatsoever, I still have chills and I failed in this year examination and writing a retest on Monday, and this time, I just googled whether there's anything I could do to score better in Maths, and that's when I read this interesting article and found out that I'm not alone. Because this is exactly like my story. I'm weak, I always get the just-pass marks, my brother is a top-scorer who is hopefully cracking a AIIMS soon and has 95% marks in his 12th grade and all, and I left a group tuition cause I was insulted and then joined a tuition where I used to be the only student, and I'm continuing that, but the thing I failed to keep is being regular. I'm never regular to the tuition because I hate maths firstly and I'm a lazy girl who spends her weekend by watching new movies, with drinks and chips and popcorn and stuff and going out every weekend for shopping with my family or friends, or going to stay at cousin's or mom's or spending quality time with my best friends or my best-friends-cum-family my cousins..Okay! I've told too much. I hate maths. No, I hated it. Not anymore. I'm going to pretend like I love it and work hard. I've got 5 days from now, that's like huge time to cover 6 lessons and then practice extra questions and sums. Well then! Let's see how I'll score and whether the hardwork will pay off! Fingers crossed! Maths!! HERE I COME BROTHER.

Hardest topic in Calculus 2?
Depending on what book you use, the order is different. If i remember correctly, series was last in our books. Topics that i remember being terrible: U-Substitution (Integrals) Integration by parts Trigonometry Substitution (Least Favorite) Volumes of Revolution These were my absolute worst parts. Calc 2 is no joke. Best thing to do is put your head in the book until you get out. It is terrible taking it twice. Some of my friends were in there 3 times. Depending on your major (mine was Mechanical Engineering) you rarely use any of that. I have used integration by parts maybe 10-15 times since (Mostly in Differential Equations) .....Grind it out, Goodluck

CONFUSED ABOUT RATIONAL EQUATIONS QUESTION? 10 POINTS!!!?
Hi! So usually when we solve these problems in class, we multiply each side by the least common denominator and cancel like terms. But in this problem, she multiplied by both and kept the like terms?? Why did she do this??
What when multiplied together equals 135 and when added together equals -24?
Since the product is positive and the sum is negative, we know that the two numbers must both be negative. In this case, the factors of 135 are 1*135, 3*45, 5*27, 9*15. The two numbers that add up to be 24 are 9 and 15. But since the numbers have to be negative, it's -9 and -15
What is the smartest way to get 200+ marks in JEE mains in 5 months?
Okay so First of all BEST OF LUCK and Most importantly Don't Come in Pressure.So 200 marks in JEE Mains is Not difficultSo If you are School Going and Not joined any Institute then You have to act smartly.Try to get most out of Chemistry and it is very easy to score and score around 80+ in chemistry by only reading NCERT Seriously.Hit on Topics that are easy to score and Very much expected i.e Physical Chemistry (Easy Numerical) Inorganic Chemistry is Must and Easy, Organic Chemistry can Be tough so try to attempt Questions you easily can.Try to Attempt less and have a higher Accuracy.Now 120 Marks And 2 subjects.So It's easy, I'll tell you.Now try to Attempt Easy topics in Physics that Are very easy, for example Semiconductor, Communication System, Modern Physics, 1D and 2D motion, Electromagnetism, Error and Measurement and Wave Optics .Try to Attempt 17–18 Questions with high Accuracy so that you can get around 65–70.Now Comes the Ghost Mathematics.Same strategy. Attempt Accurately.Hit on Topics like Trigonometry, 3D, Vectors, Statistics, Set Theory, Mathematical Reasoning, PNC Probability ( if you can then it would be great) and Quadratic Equations and Matrices and Determinants.If you attempt these topics sincerely then You can definitely attempt 15–16 Questions and get 60 marks around.So that's how it would be easy for you to score 200 above in JEE mains.Attempt previous mains Seriously to Built EXAM TEMPERAMENT.Best Of Luck.
