Question $7$:

Use matlab to solve this :

Write a script to plot the function $f(x)=si{n}^2(x)cos(2x)$ and its derivative, both on

the same plot, for $0x2.$ Plot $f(x)$ with a solid line, and $f^{\text{'}}(x)$ with a dashed line

with different colors. Add a legend and label the axes.

Hint: use linspace to create a vector of $x$ values then feed that vector, separately, to

your $f(x)$ and $f^{\text{'}}(x)$ to create $y$ values.
