    Undergrad Is the School Definition of a Tangent Line Always Accurate in Calculus?

    When i was at school i used to think that any line that touches a curve at only one point is called as the tangent at that point to the curve! But after reading derivative i think this definition of tangent is not correct at all conditions! For example, x-axis cannot be called as tangent at...

    Graduate Epsilon-delta definition of limit

    Thanks jgens! But the way you explained is little hard for me understand( as i am not used to all mathematics you used here). Its my weakness not yours!:(

    Graduate Epsilon-delta definition of limit

    Thanks a lot STEPHEN, the example you gave here is enough to clarify my confusion! I will consider your advice from now on!

    Graduate Epsilon-delta definition of limit

    Then can you please tell me (in short) how limits are actually defined ( cause i know only that old fashioned definition of limit). Please!

    Graduate Epsilon-delta definition of limit

    Ya I think the same but still not sure about it!

    Graduate Epsilon-delta definition of limit

    Yeah you got my question! ya, we may get a complicated function of δ in terms of ε like in examples you stated above but in these examples also δ decreases by some amount as ε is decreased by some other amount.isn't it? Logically also, if we want limit of a function f(x) at any point c ( and...

    Graduate Epsilon-delta definition of limit

    Thanks chiro! Ya, if they are inversely proportional to each other then as ε→0 ,∂→∞ (because ∂= a/ε) so rather than moving toward any point (say c) the interval around c ,where we want limit if it exists,will move away from c when ε is decreased so i guess ε and ∂ can never be inversely...

    Graduate Epsilon-delta definition of limit

    While solving problems regarding Epsilon-delta definition of limit from my textbook i found that every answer was like ε= a×∂,where a was any constant.Is it necessary that ε should always be directly proportional to ∂ for limit to exist?? Cant they be inversely proportional? If they can please...

    Undergrad What is the physical meaning of electric dipole moment?

    For example ,if u ask what is energy,we can say like its capacity of doing work!for force we can experience it.Like them what does electric dipole moment signify ?? U mean that its just collection of symbols named as electric dipole moment?o_0

    it experiences torque.

    Undergrad What is the physical meaning of electric dipole moment?

    What is the physical meaning of electri dipole moment? What does it tell us about the dipole? Please don't just throw away mathematical equation (p=qd r_hat); help me to get its physical sense!

    Graduate Does Y See Events in X as Simultaneous?

    yoU mean Y viewing from his rest frame B to X (throug a telescope or by any other) will see events occurring simultaneously or at different times in X??

    Graduate Does Y See Events in X as Simultaneous?

    I have already mentioned that the events are simultaneous in X frame(sorry if it wasn't clear). But how will Y predicts that both events are simultaneous in X frame as he will see that X is moving towards event red with same velocity v relative to him??
