Quick MATLAB help --> Setting a termination point on a plot. I have this kinematics problem on dropping a ball from a building a few meters high. When I plot the position vs time graph, it starts at let's say 50 meters high, I get a plot of an upside down parabola, as expected, but my plot...

Hi This has got to be easy but I can't find the answer anywhere. How can I use 'plot' where the x-axis does not include the end points 0 or 5? All the examples I see are things like x=[0:0.1:5]. Thanks in advance.

For example, how would I plot the fixed vector <3, 4, 3>? I'm not sure if I'm using the correct language; I mean the vector with its tail at (0, 0, 0) and head at (3, 4, 3).Also, how would I plot the plane 11x + 19y + 39z = 88?

The following Mathematica code generates a highly oscillatory plot. I would like to plot only the lower envelope of the plot but do not know how. Any suggestions wouuld be appreciated. tk0 = \[Theta]'[t]*\[Theta]'[t] - \[Theta][t]*\[Theta]''[t] tk1 = \[Theta]''[t]*\[Theta]''[t] -...
