Shroud of Turin

The Shroud of Turin is believed to be the burial shroud of Jesus, marked with unexplained markings of a whipped, crucified man.

Jesus freeing the faithful

Before Jesus rose, he freed all people who had been faithful to God, like Abraham and Moses, in the place of the dead.

Witnesses of Jesus's rising

No one saw Jesus rise, but witnesses found his burial clothes in the empty tomb and later saw Jesus himself.

Eternal Life

Jesus rose with a new and eternal life, unlike Lazarus and the daughter of Jairus, who died again after being raised.

Study Notes

  • A vectorial function of a real variable is described by $\overrightarrow{r}: I \subseteq \mathbb{R} \longrightarrow \mathbb{R}^n$.
  • Each real number $t$ in the domain of $\overrightarrow{r}$ is assigned a vector $\overrightarrow{r}(t)$ in $\mathbb{R}^n$.

Example of a Vectorial Function

  • The function $\overrightarrow{r}(t) = (t^2, t^3)$ maps each real number $t$ to the vector $(t^2, t^3)$ in $\mathbb{R}^2$.

Components of Vectorial Functions

  • For a vectorial function $\overrightarrow{r}(t)$ in $\mathbb{R}^3$, it’s expressed as $\overrightarrow{r}(t) = (f(t), g(t), h(t)) = f(t) \overrightarrow{i} + g(t) \overrightarrow{j} + h(t) \overrightarrow{k}$.
  • $f$, $g$, and $h$ represent the component functions of $\overrightarrow{r}$, and they are real functions of the variable $t$.

Example of Vectorial Function Components

  • The vectorial function $\overrightarrow{r}(t) = \cos(t) \overrightarrow{i} + \sin(t) \overrightarrow{j} + t \overrightarrow{k}$ has components $f(t) = \cos(t)$, $g(t) = \sin(t)$, and $h(t) = t$.

Limit of a Vectorial Function

  • If $\overrightarrow{r}(t) = (f(t), g(t), h(t))$, then $\lim_{t \to a} \overrightarrow{r}(t) = (\lim_{t \to a} f(t), \lim_{t \to a} g(t), \lim_{t \to a} h(t))$, given that the limits of the component functions exist.

Example of Limit Calculation

  • For $\overrightarrow{r}(t) = (\cos(t), \sin(t), t)$, the limit as $t$ approaches 0 is $\lim_{t \to 0} \overrightarrow{r}(t) = (\lim_{t \to 0} \cos(t), \lim_{t \to 0} \sin(t), \lim_{t \to 0} t) = (1, 0, 0)$.

Continuity of a Vectorial Function

  • A vectorial function $\overrightarrow{r}$ is continuous at $a$ if $\lim_{t \to a} \overrightarrow{r}(t) = \overrightarrow{r}(a)$.
  • In terms of components, $\overrightarrow{r}(t) = (f(t), g(t), h(t))$ is continuous at $a$ if and only if $f$, $g$, and $h$ are continuous at $a$.

Example of Continuity

  • The function $\overrightarrow{r}(t) = (\cos(t), \sin(t), t)$ is continuous across $\mathbb{R}$ because its component functions are continuous on $\mathbb{R}$.
