How is this proven

[AdamS]

I read that

sin(h)
------- = 1
h


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 here (http://people.hofstra.edu/faculty/Stefan_Waner/trig/triglim.html) 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
