3D Plot There are several types of 3D plots: plot3D, contour3D, plot_wireframe, plot_surface, and plot_trisurf. Operations on 3D plots require additional packages such as mplot3D located in the folder site-packages/mpl_toolkits. To create a 3D Cartesian plot, you need to make three parallel arrays of x,y, and z coordinates that specify points. You can do it in various ways. The simplest method is to use the plot3D that takes three parallel arrays corresponding to x,y, and z coordinates of the points. Example1. Archimedes Spiral in 3D Based on the previous problem, answer the following questions: Please round numbers to integers. What is the first value in the array z ? What is the last value in the array z ? What is the last value of the array x ? What is the last value of the array y
