a.1 Create a MATLAB script that generates x-values from - to using linspace with 200 data samples. Define four different y-values as follows:

y 1 =sin ^2 (x) y 2 =cos ^2 (x) y 3 =sin(x)cos(x) y 4 = 1/(1+e ^x)

Plot these four curves on the same graph using different line styles and colors. Include appropriate labels for the x-axis and y-axis, a title for the plot, and a legend.

make sure the output plot looks likes the given plot.
