Question

Using “help” and Plotting Graphs: Read up on the plot3 function and reference the built-in example. This can be done by typing: help plot3

Given that 0 < t < 30, use this function to plot a circular helix with the following components:

x(t) = cos(2t) y(t) = sin(2t) z(t) = 2t

Make sure you choose enough points to make the curve smooth.

Specifically, how do i make the curve smooth? I keep getting a series of lines that appear to make up the helix but it is not smooth at all.

This is Matlab by the way.

Explanation / Answer

Increasing the number of points will surely help in making the curve smoother. Just keep increasing the number of points till the curve is smooth. You can also select smoothing spline option from the drop down list of the model type, in the curve fitting application menu.
