[tex]d=\left( \left. \frac { { d }x }{ { d }t } \right| _{ 0 } \right) t+\left( \left. \frac { { d }^{ 2 }x }{ { d }t^{ 2 } } \right| _{ 0 } \right) \frac { t^{ 2 } }{ 2 }[/tex]
is supposed to be the same as writing
[tex]d=vt+a\frac { t^{ 2 } }{ 2 }[/tex]
The first equation seems to use the definite integral, but there's no upper limit?
Furthermore, shouldn't it be the following?
[tex]d=\frac { { d }x }{ { d }t } t+\frac { { d^{ 2 } }x }{ { d }t^{ 2 } } \frac { t^{ 2 } }{ 2 }[/tex]
