Chapter 10, Problem 2P

A staircase of height h is modeled by the parametric equations:

hi

x = r cos(t) y = r sin(t) $z=\frac{ht}{2\pi n}$

where r=h[2 +5sin)(t/8)]/10, n = 4, and h = 50m is the staircase height. Make a 3-D plot (shown) of the staircase. (Create a vector t for the domain 0 to 2pn, and use the plot 3 command.)
