Question

Why is Sin(x)/x zero when x=0?

Answer 1

sin(x)/x is not zero when x=0,
it's undefined or inderminate form 0/0

Answer 2

however, as x->0, sin(x)/x -> 1
we call it limit.

Answer 3

my bad, i meant to say why is sin(x)/x equal to 1 when x=0

Answer 4

\( \frac{\sin(x)}{x} \not = 1\)
\[ \lim_{x \rightarrow 0} \frac{\sin x}{x}= 1\]
