    Which Standalone Software Converts Handwritten Math Equations for Homework?

    MathType claims to be able to do that, but I haven't found out how to use it yet, despite using the software for some time already.

    Logarithms(i hope this is in the right section)

    1) Log is there, simply to show you are taking the logarithm. If you just write 4, how would anyone know what you are doing? The log is more like an operator, so there is no value. 2)Yes and you solve for that something. 3) I'm not sure about that. I agree with you. The current high...

    Which Standalone Software Converts Handwritten Math Equations for Homework?

    I recommend MathType. It allows you to just drag the symbols from a template, use the shortcut keys (I think you can customize that), or use LaTex if you know. Pretty convenient.

    Difference between codomain and range

    For a simple idea, consider this http://www.mathsisfun.com/sets/domain-range-codomain.html It isn't really formal, but since you want to get your head around it, this should provide a decent intuition. Hope it helps.

    Haha, luckily I'm going on vacation to the countryside soon, so that would give me a couple of good nights if it doesn't rain :)

    That's my problem, there is too much clouds in my area. Whenever I look out at night, I usually can't see a thing, not even the brightest stars or planets :(

    Alternative for sphere volume:FAIL

    Then you should, so you can learn understanding instead of just memorising integrals.

    Alternative for sphere volume:FAIL

    To get an idea and basic concepts, try Khan Academy. If you wan to learn the "standard" way, any university calc textbook will do. I'm not sure about online ones, but try Paul's Online Maths Notes http://tutorial.math.lamar.edu/sitemap.aspx PS Presuming you've learned differentiation already.

    Calculating Reaction Force: Box on Rigid Wall with Applied Force of 100 N

    Good point I almost forgot. Guess I'm too used to problems dealing with kinetic friction.

    Why is Division harder than Multiplication?

    I think (from personal experience) is that to do division you need to be familiar with your multiplication.

    Calculating Reaction Force: Box on Rigid Wall with Applied Force of 100 N

    I don't quite follow you, since in the end you are not so interested in the friction but rather the force the wall exerts? Anyway, I will try to answer with what I understand. Please clarify if this is not what you meant. The box is not moving, so it is in equilibrium. Considering all the...

    Has PF Changed? Machine Tool Industry Perspective

    I doubt doing this will get you any of the above. You can view things positively or negatively. From your record of number of posts, all you have done here in the forum is complain? I am not an experienced member here, I only joined months ago. However I find lots of threads NOT locked and the...

    How Does Mass-Energy Equivalence Relate to Gravity?

    I think the OP meant how this equation is derived, more specifically how c^2 was derived.
