    High School Magnetic attraction to ferromagnetic material

    Yes, wikipedia did help but it's kind of complicated :) Thanks though!

    High School Magnetic attraction to ferromagnetic material

    Thanks! But why do electrons produce a magnetic field when they orbit?

    High School Magnetic attraction to ferromagnetic material

    Can you explain in more detail?

    High School Magnetic attraction to ferromagnetic material

    Why do magnets attract ferromagnetic materials only? Why not other materials as well?

    Why are Some Genes Dominant Over Others?

    Okay, but what causes this difference? I mean why do the genes for light eyes cause pigment to appear in just the back layer. And thanks for correcting my terminology!

    Why are Some Genes Dominant Over Others?

    What makes a gene dominant over another? Like why is the gene for brown eye dominant over the one for blue eyes? My teacher says it is "just like that" but I'm not so sure. IS there a reason for this?

    Undergrad Why can't we integrate 1/(1+x²) and √(1+x³) the normal way?

    Wow! That is so complicated. But thanks for your help.

    Undergrad Why can't we integrate 1/(1+x²) and √(1+x³) the normal way?

    Thanks a lot for all your advice! But why is dx really important and what's the reason that it's there?

    Undergrad Why can't we integrate 1/(1+x²) and √(1+x³) the normal way?

    What are the integration techniques that I could use to find the antiderivatives of these functions, apart from the trapezoidal rule??

    Undergrad Why can't we integrate 1/(1+x²) and √(1+x³) the normal way?

    No, i haven't studied integration by parts or trigonometry substitutions yet. I have studied integration of exponentials and logarithms and simple functions.

    Undergrad Why can't we integrate 1/(1+x²) and √(1+x³) the normal way?

    "2 examples which you cannot integrate with your knowledge so far are ∫1/1+x2 and ∫√1+x3. You need to use the trapezoidal rule for this" This was written in my textbook and I really can't understand what it means! I mean why can't we integrate it in the normal basic way?
