Derivatives, Limits, and Arc Length in Calculus

$e^x imes ( an(x) + rac{1}{ an^2(x) + 1})$ (correct)

$e^x imes ( an(x) + rac{1}{ an(x)})$

$e^x imes ( an(x) - rac{1}{ an(x)})$

$e^x imes ( an(x) - rac{1}{ an^2(x) + 1})$

$rac{ ext{erf}(1)}{ ext{erf}(1)^2}$

$rac{ ext{erf}(1)}{ ext{erf}(rac{1}{ ext{erf}(1)})}$

$ ext{erf}(1)^2$

$rac{ ext{erf}(1)}{2}$ (correct)

$rac{ an(0)}{0}$

Undefined

0

1 (correct)
