I finally published my chrome extension. What it does: -Adds a button 'Notebook' next to 'Draw' button to open up notebook -You can store pieces of text (notes) in your notebook. -You can search your notebook for a particular note. -You can insert the note into the reply. -You can import and export your notebook, to back it up or share with others. Where to get it: https://chrome.google.com/webstore/detail/open-study-notebook/nmdboeolmlhaaepahmeklccofcbbmpdc Filling up notebook: Notebooks start out with only one benign note. You can import what I have in my notebook if you'd like: ``` [{"title":"Welcome","body":"Thank you for using the OpenStudy notebook extension."},{"title":"Slope Point Formula","body":"The equation of a line with slope \\(m\\) that goes through the point \\((x_0,y_0)\\) is given by: \\[\ny-y_0 = m (x-x_0)\n\\]"},{"title":"Tangent Line Formula","body":"The equation of the tangent line to a function \\(f(x)\\) at \\(x_0\\) is given by: \\[\ny-f(x_0) = f'(x_0) (x-x_0)\n\\]"},{"title":"Definition of the Derivative","body":"The derivative of a function \\(f(x)\\) is defined as: \\[\nf'(x) = \\lim_{h\\to 0}\\frac{f(x+h)-f(x)}{h}\n\\]"},{"title":"Definition of the Limit","body":"The limit: \\[\n\\lim_{x\\to a}f(x) = L\n\\]Is defined as: \\[\n\\forall \\epsilon\\; \\exists \\delta\\;\\\\\n\\forall x\\quad 0<|x-a|<\\delta \\implies |f(x)-L|<\\epsilon\n\\]That is: \nIf I come up with an \\(\\epsilon\\) you will always be able to give me a \\(\\delta\\) such that\nWhenever \\(x\\) within your \\(\\delta\\) range, \\(f(x)\\) will be be within my \\(\\epsilo...n(x^n)' &=&nx^{n-1}\\\\\n(e^x)'&=& e^x\\\\\n(a^x)'&=& a^x\\ln(a)\\\\\n(\\ln(x))'&=& \\frac{1}{x}\\\\\n(\\sin(x))'&=& \\cos(x)\\\\\n(\\cos(x))'&=& -\\sin(x)\\\\\n(\\tan(x))'&=& \\sec^2(x)\\\\\n(\\sec(x))'&=& \\sec(x)\\tan(x)\\\\\n(\\csc(x))'&=& -\\csc(x)\\cot(x)\\\\\n(\\cot(x))'&=& -\\csc^2(x)\\\\\n\\end{array}\n\\]"},{"title":"Heaviside Function","body":"The Heaviside unit step function is defined as: \\[\nH(x)=\\begin{cases}\n0&x<0\\\\\n1&x>0\n\\end{cases}\n\\]A piecewise function can be converted to a non-piecewise using it:\n\\[\n\\begin{cases}\nf(x)&x<c\\\\\ng(x)&x>c\n\\end{cases}\n\\quad =\\quad f(x)+[g(x)-f(x)]H(x-c)\n\\]\nProof: \\[\n\\begin{split}\n&\\begin{cases}\nf(x)&x<c\\\\\ng(x)&x>c\n\\end{cases}\\\\\n=&\nf(x) +\n\\begin{cases}\n0&x<c\\\\\ng(x)-f(x)&x>c\n\\end{cases}\\\\\n=&\nf(x) +\n(g(x)-f(x))\\begin{cases}\n0&x<c\\\\\n1&x>c\n\\end{cases}\\\\\n=&\nf(x) +\n(g(x)-f(x))\\begin{cases}\n0&x-c<0\\\\\n1&x-c>0\n\\end{cases}\\\\\n=&f(x)+[g(x)-f(x)]H(x-c)\n\\end{split}\n\\]"}] ``` Where are notes stored? Notes are stored in a JSON array using localStorage. If you delete your localStorage without backing up your notebook, then all the notes will be gone. Firefox/Other Browsers: I dunno if I'll make a version for other browsers, because I don't really use them. You're welcome to make look at my code and make your own version. GitHub: The code is open source, so you can look at it anytime you want. https://github.com/wiogit/OpenStudyNotebook

    It looks cool and promising. I am also trying to get rid of the long-winded coding required for latex display utilizing mathtype software. All equations may be exported or converted into MathML or varying Latex versions using the built-in translation of MathType. There will be no plug-in requirement. However, this is only beneficial for those who have MathType software installed into their Mac or Windows.

    The editor is fine. I am looking for ways to be able to enter equations faster. it is a pain to use the equation editor and it doesn't allow a carriage return (new line). There are a lot of symbols missing also. Having to just click the quadratic formula instead of entering them character by character saves a lot of trouble

    I just made a note with the quadratic formula in it.
