    Is the Sine Function Linear in Small Domains?

    Sine function linear?? I have a problem concerning trigonometry and calculus but I just need to know my question's answer to solve it. I would like to know: can a sine function be construed as a linear function in a very small domain i.e increments of 0.0001?? Thank you so much in advance and...

    Undergrad Can the Attractive Force Between a Metallic Object and a Magnet be Quantified?

    This may be a dumb question but I am so lost and would appreciate any help! Is there a way to quantify the attractive force between a metallic object and a magnet? With numbers not qualitatively? I was under the impression that with a metallic object everything was microscopic so itd be...

    Undergrad Understanding Period and Frequency in Composite Sine Functions

    Thanks DonAntonio :D But do you happen to know any other relationships apart from Simpsons' or Werner's? My dilemma is, given a graph, how would you figure out what it is made up of? i.e what sine functions were added to produce that graph? I just need a hint - do you happen to know any...

    Undergrad Understanding Period and Frequency in Composite Sine Functions

    Hey all! I have a question concerning the addition of 2 sine functions. Could anyone point me to the right direction as to what happens to the period and frequency when two sine functions are added together? Note: when adding, these two functions possesses two different frequencies. Thanks...

    Undergrad Magnetic field induction enigma?

    Hello all! I was researching about magnetism to investigate the processes which occur when a magnetic object is stuck onto a magnet. I gather that this will be due to the alignment of magnetic domains and as such, the sum of all these electron spins in one direction will cause the attraction to...

    Undergrad Linking current-carrying wires to magnets

    Thanks a lot tiny-tim! :D Does that mean magnets exhibit magnetic properties solely due to synchronised movement of electrons i.e aligned domains? So this means that a current is not required like a solenoid? Or do aligned domains produce a current? Sorry, I'm nearly there...I think :)

    Undergrad Linking current-carrying wires to magnets

    This may be an obvious question but I have no idea: How can anyone link current-carrying wires (solenoids) and its formulae, to magnets?! All I've researched so far points out that magnets have their own stable magnetic field, attributed to the alignment of spins of the electrons of the atoms...
