Plot the "moment curve" f(t)=(t,t^2,t^3) over the interval 1≤t≤2 and a tangent line at the point when t=1. Include both plots in the same display, with the moment curve red and the tangent line blue.
 

Plot the boundary of the rectangle with bounds 1≤x≤4 and 2≤y≤3 by parametrizing and plotting all four boundary segments in the same display
