## Function

{[x(t) = cos(t), y(t) = sin(t), z(t) = t], [x(t) = cos(t+Pi), y(t) = sin(t+Pi), z(t) = t]}

## Domain

tis an element of the set of allReal numbers

## Graphs

## Derivative

With respect tot: {[-sin(t), cos(t), 1], [sin(t), -cos(t), 1]}Critical points are formed where all the derivatives equal 0. These critical points may be minimums, maximums, or saddle points. Since 1 will never equal 0, there will be no critical points. This means that there are no minimum or maximum points. This is the same for both equations.

## Integral

With respect tot: {[sin(t), -cos(t), (], [^{1}/_{2})t^{2}-sin(t), cos(t), (]}^{1}/_{2})t^{2}

## Interesting Features

This plot shows a double helix. The plot contains the standard helix and a second helix rotated Pi radians around. This is very similar to the double helix structure found in human DNA.
