plot the function s = 2 sin(3t+2) + √𝟓𝒕 + 𝟏 over the interval 0 ≤ t ≤ 5. Put a title on
the plot, and properly label the axes. The variable s represents speed in feet per second; the variable t
represents time in seconds

Here are the tools you'll need. These are basic Matlab 101 tools that you'll use a lot in Matlab.
  1. Define t using the colon opertator or linspace.
  2. Put t into your equation; you'll obvsiously need to insert some operators such as 2*sin(.......
  3. Use plot() to plot s as a function of t
  4. Use xlabel(), ylabel() to label the axes.

X=0:t:5; S=2*sin(3*t+2)+sqrt(5*t+1); Plot(X,S),Xlable('X'),Slable('S')

This suggestion will not work:
  • 0:t:5 is not necessarily the complete interval. See:
t = 0.35;
X = 0:t:5;
X(end)
ans = 4.9000
prefer X = linspace(0, 5, 100) instead.
  • Matlab is case-sensitive: There is neither a "Plot" command, nor "Xlable" nor "Slable". You mean: plot, xlabel, ylabel.
