3D Plotting Task using Matlab

Task: 

The popular amusement ride known as the corkscrew has a helical shape. The
parametric equations for a circular helix are:           
x = a cos t
y = a sint t
z = b*t
Where a is the radius of the helical path and b is a constant that determines the
tightness of the path.
For this homework, plot the x, y, and z variables.
Use 0 ≤ t ≤ 10*pi, b = 0.1 and a = 1.25. Print the graphs, label your axes and title of
the graph.

Solution:

% given values of constants :
t = 0:0.1:10*pi;
b = 0.1;
a = 1.25;

% given equations of x , y , z :
x = a * cos(t);
y = a * sin(t);
z = b * t;
