    How Is MS Word related to HTML and CSS?

    Do you know if kindle translates Word nicely from word? I did view a HTML word file and i see your point, maybe writing ebooks in HTML and CSS is the way to go, i just need to find out which subset of HTML and CSS is allowed on kindle devices.

    How Is MS Word related to HTML and CSS?

    Wau that's a lot of files, thank you for the demonstration, so word can convert from Words coding language to XML, and today to HTML. So what is the inherint/original coding language that word uses for formatting fx heading 1, body text etc?

    How Is MS Word related to HTML and CSS?

    Just wondering: When i write a book in MS Word and save it as a webpage file (html) It seems that all the formatting i chose in MS Word (bulletons, indents, headings) perfectly translates to HTML and CSS, so just wondering Is HTML and CSS built into MS Word? Does MS Word work like a BROWSER...

    Foundations Recommended Math books as preparation for bachelor in math?

    Sounds almost imtimidating. All i know is high school math and then the first 250 pages of Keisler (infinitesimal approach). I was hoping to become a high school teacher in math but I need to major in mat to do that where I'm from. I'm a very visual learner, what exactly will i be facing during...

    Foundations Recommended Math books as preparation for bachelor in math?

    Thank you very much guys, So I'll skip the book of proof: Start with Infinite.Curves recommendation http://www.mathdb.org/basic_calculus/BasicCalculus.pdf Then try Allendoerfer and Oakley's book: after that.

    PHP HTML, php and css code in ebook, proper formatting?

    Thank you for the reply, I might have to learn latex, seems like there is scarce guidance on proper formatting for ebook publishers who want to publish code language.

    Foundations Recommended Math books as preparation for bachelor in math?

    For a long time I've been debating whether to study Physics or Math at university (Bachelor), but I'm going to jump into math this summer. I have this feeling that preparing for "logical thinking" and mathematical language/terminology would be a good idea, since all i have is my 3 year old...

    PHP HTML, php and css code in ebook, proper formatting?

    That's very nice to know. I know a lot about html and css but very little about ebook publishing. How can CSS and HTML help me make an ebook that reflows based on screen size?

    PHP HTML, php and css code in ebook, proper formatting?

    Hi, I want to write an ebook on CSS, HTML and php, and I'm using a RTF copy/paste plugin to my code editor so i can copy and paste code directly into MS Word from my code editor. I'm just wondering: Can i write the whole book in MS Word and then directly upload it to amazon, for ebook readers...

    Lunar and Solar eclipse - same times a year?

    Interesting, you say that the moon undergoes precession with a period of 18.6 years, Does that mean it rotates like a cone just like the earth 26.000 Year precession period?

    Multiplying mass as kg and grams= 2 different results?

    Hi, I'm just wondering. If you mulitiply 1kg with 0.5kg you get 0.5kg But if you do the multiplication in grams you get 1000g *500g = 500.000g = 500kg. a dompletely different result. Why is that? How do you avoid this problem?

    Astronomy Good ancient to modern history astronomy books?

    Hi, Can anyone recommend some good ancient astronomy books (from around 8000BC-0) that that are historically correct (perhaps springled with a few translations from older writings) with visual images, and that show in some detail how different calculations, and observations were made? It would...

    Lunar and Solar eclipse - same times a year?

    Yes but I'm not asking if they can happen the same time. I'm asking if the position of the earth on its orbit around the sun is then same when either solar eclipse or lular eclipse happens? So are there 1 or 2 specific positions on the earths orbit where the moons and earths orbital planes...

    Lunar and Solar eclipse - same times a year?

    Hi, Just wondering: The lunar orbit around the earth is tilted 5.1 degree with respect to the earths orbit around the sun (as described in the video), so only at 2 times during the year the earth is aligned with the sun such that lunar eclipses can happen IF the moon is behind the earth...

    Mechanical advantage of a mountain climber (pulley)

    Hi I have a hard time undersanding the mechanical advantage of this pulley system (in the video below): I understand that when a person is holding you, then the mechanical advantage is 2, because 50% of the weight or Load is on the rope going from the harness to the top left anchor point, and...

    Archimedes Derivation: Law of the lever

    Thank you very much! There is one more thing i can't seem to understand: I understand that little w is the weight of the object on the lever, but right next to little w there is a big W pointing down (on the left side). What does the big W mean? And what is it doing on the left side?

    Archimedes Derivation: Law of the lever

    Hi, I'm watching a talk about Archimedes Law of the lever, and I was wondering: Does anyone know how the formula d=w/2w/b-a) was derived from the lecture drawing at 9.00 min in? The speaker just skips the algebraic derivation.

    Writing correct mathematics -- functions within functions...

    A last question: If you define a function f to have the equation f(x) = 2x is it then true that the variable y=f(x) differs from f, because f is a function (not a number) and y is a number? So when we take f(x)= (1+2x)^2 and call u=(1+2x) then it would be wrong to write f=u^2 because f is...

    Integration: Can't understand when to use Power rule.

    Thank you so much! So what you are saying is if i don't know what h(x) is i can't integrate it with repsect to x, So if f(x)=(2+5x)^2 then h=2+5x so i can't evaluate ∫h^2(x)dx but I can evaluate ∫h^2dh . Why is it we can't evaluate ∫h^2(x)dx ? Is it impossible or is it just because it's really...

    Writing correct mathematics -- functions within functions...

    Hi I'm a bit confused about some mathematical notation If i write f(x)=(2x^2 + 10)^4 And i define u= 2x^2 +10 u^4 = f(x) Would it then be correct to write f(u)= u^4 Or would i get f(u)= 2(u)^2 +10 = (2(2x^2 +10)+10)^2 Should i define u^4 = f(x) first? Would it then be correct...

    Integration: Can't understand when to use Power rule.

    Just at last question regarding notation - The dx, du, dh etc. if f(x)=(1+5x)^2 then h=(1+5x) f(x)= h^2 But regarding the function h, when should i write dh vs dx? If i write ∫h^2 I would add dh but if i write ∫(h(x))^2 should i then add dx? What is the difference between writing...

    Integration: Can't understand when to use Power rule.

    +Thank you, I understand what I didn't understand 1) If u is a independant variable f(u) depends on u Then ∫f(u)du =F(u) +C And in this case du is always equal to 1 because the differential of a variable d(u)=u'du=1*d or d(x)=x'dx=dx So if f(u)=u^4+u^2 Then the sum rule and power rule...

    Integration: Can't understand when to use Power rule.

    Hi thank you for reply: What do you mean by "Note that this equation is true whether or not u is a function of x?" Do you mean if u was a function of t instead? If i multiply the brackets its easy, (1/x + x)*(1/x + x) = 1/x^2 +2+x^2 and the integral of this is very easy but I feel as if this...

    Integration: Can't understand when to use Power rule.

    Homework Statement Hi I have a really hard time understanding when and how to use the Power rule when integrating My book states that if u is a function of x, then the power rule is given by: ∫urdu = (ur+1)/(r+1)+c First: I do understand that if u=2x Then the differential du=u'(x)dx =2...

    Hi I'm tying to understand notations in Integration, and would really appreciate some help making sure that my understanding is right. My books writes Let u and v be functions of x whose domains are an open interval I, and suppose du and dv exist for every x in I. Then it defines 1) ∫(du)=...

    Intermediate Value Theorem

    Hi, I'm confused about an explanation in Elementary Calculus, the infinitesimal approach regarding Intermediate Value Theorem. The explanation: Suppose g is a continuous function on an inverval I, and g(x) # 0 for all x in I (i) If g(c) > 0 for at least one c in I, then g(x) > 0 for all X...
