How to be good in Mathematics?
I tried to study everyday..But i always get Mental Block during the Exams...and I'm really not good in numbers..especially problem solvings..please help me..
What are the best books for beginners to learn maths step by step from the basics until the expert level?
How to Be Good at Math: Your Brilliant Brain and How to Train ItHow to Be Good at Math uses an innovative visual approach to explain and define all the basic math concepts taught in schools for children aged 7–11.Unlike other math guides, dictionaries, and workbooks, How to Be Good at Math presents topics in dynamic, colorful graphics reinforced by real-life examples and fascinating facts. Ranging from second-grade topics such as learning odd and even numbers to harder sixth-grade-level problems like angles and algebra formulas, the innovative, highly visual approach makes basic math easier to understand than ever before.How to Be Good at Math is perfect for reluctant mathematicians, as well as providing a fun, reliable reference to look things up.
Math help!! You need to use equations please show steps to learn how to solve thanks!?
1. You own a collection of dimes and quarters that is worth $3.45. If there are 3 more dimes than quarters, how many of each coin are there? 2. A truck driver plans to drive 805 km. After 5 h, she travels 470 km. If she continues driving at the same speed, will she arrive at her destination within 9 h of her starting time? Explain. 3. Because you failed to study for your first quiz of the marking period, you got only 1 out of 10 for the quiz. If you get a perfect 10 on all your other quizzes, how many do you need to take to bring your mean score up to 9?
Which steps should I follow to learn calculus with basic math knowledge as a starting point?
Well I can recite the classical way it is done at universities in Germany (at least for physicists and engineers):1. Set theory2. Real and complex numbers3. Relations, functions (fundamental definitions)4. Elementary functions like polynomials, exponential, logarithmic, trigonometric functions5. Sequences and series6. Continuity of functions7. Differential calculus8. Power series and Taylor polynomials9. Integral calculusAnd a personal note on my preferred method of studying: Just reading the theory in books or lecture notes is really ineffective unless you do it extremely thoroughly and try to understand every single detail. What has worked best for me so far:1. Quick review of the topics, pretty much in order to know what concepts exist and where to find the explanation.2. Problems, problems, problems. Non-stop. You will quickly get a feeling for what you can and what you cannot do and will be automatically forced to grasp the concepts by studying them thoroughly. That is the beauty of mathematics.
Can someone help me solve this math problem step by step?
I'll try, but I am used to writing them in descending order, so I'm going to rewrite it. It won't change the value or the steps: -63b^2+17b+20 ok, that's ugly. We can sit here and try to dissect it, but there are so many ways it can go. We can use two other methods, the quadratic formula or completing the square. Before I continue, I'm going to give you a link to a math help site that I often use myself: http://www.purplemath.com/modules/index.htm. Because the coefficient of b^2 is negative, we should use the quadratic equation. That's hard to type, but for equations in format ax+by=c, it's -b +or-[sqrt(b^2-4ac)]/2a The b is not your variable. Let's put your equation into ax+by=c format: -63b^2+17b+20=0, subtract 20 from both sides: -63b^2+17b= -20 Now let's fill in the numbers into the quadratic formula: -17 +or-[sqrt(17^2-4(-63)(-20)]/2(-63) whew! start multiplying -17 +or-[sqrt(289-5040]/126 -17+or-[sqrt(-4751)]/126 Now this is where I get a bit rusty, I know you have to factor out an i from that sqrt(-4751), I THINK you do this: sqrt(4751*-1) and you get 68.93i(approx), so, not forgetting to divide by 126, the final answers should be: -17+(68.93/126)i or -17-(68.93/126)i and to do the division, -17+.55i or -17-.55i and that's as far as you can go. wpf.
