How is this proven

  1. Sep 15, 2004 #1
    I read that

    ------- = 1

    If h = 1 then
    my Calc shows that sin(1) = .8414709848
    if we then divide that by 1

    we get .8414709848

    so how is it supposed to be 1?

    I put my calc in Radian and Degree mode, neither give the result of 1.

    You have probably misread. It probably said "the limit of sin(h)/h as h tends to zero, is 1". Click http://people.hofstra.edu/faculty/Stefan_Waner/trig/triglim.html [Broken] for a proof.

    if you read something and you not sure of what youi've read, try working with what youi've got: here you're saying that sin(h)=h which can't be true.l
