Consider {{MATH_133}}. Fill in the tables
below {{CMD_134}}rounding to three decimal places{{CMD_135}}:
{{MATH_136}}
We may rush and say that, based on the table above,
{{MATH_137}}
But, recall the definition of the limit: {{MATH_138}} is the limit if the value of {{MATH_139}} is as close as one wishes to {{MATH_140}} for
{{CMD_141}}all{{CMD_142}} {{MATH_143}} sufficiently close, but not equal to, {{MATH_144}}.
From this table we can see that {{MATH_145}} is as close as one wishes to {{MATH_146}} for {{CMD_147}}some{{CMD_148}} values {{MATH_149}} that are sufficiently close to {{MATH_150}}.
But this does does not satisfy the definition of the limit, at least, not yet.
But, wait! Fill in another table, {{CMD_151}}rounding to three decimal places{{CMD_152}}.
{{MATH_153}}
What do these two tables tell us about
