Practical applications of differential equations require technical tools. For this course, the technical tool employed is MATLAB. MATLAB is an interpreted language. Programs may be easily written and modified with the built-in integrated development environment and debugger. If you are unfamiliar with MATLAB, the activities in the class have been designed to introduce you slowly to key concepts and operations.

Plot the function as a red line and turn the plotting grid on. Make sure to label both axes and title your figure. Step Stop O RUN Problem 2: Use MATLAB to plot the functions z(t) = e, 2(t) = 2u(t+1), and z3(t) = 0.5 sin(7t) for t= -2 to 2. Plot z (1) function as a green line, z(t) as a black line, and z3(t) as a magenta line and turn the plotting grid on. Make sure to label both axes, title your figure, and turn on the plotting legend.
