Plot $.$ Use the plot to solve the equation $.$

Plot over $.$ Note that we need to use "array operations".

Plot $.$ The plot has poor quality. How do we improve it$?$

Plot over the range $.$ Do you notice anything odd? Fix it$.$

Plot x given y

Suppose $.$ It is hard to come up with an expression for in function of to plot it$.$ But for ploting purposes, we don't care what came first or $.$ We can produce $-$data first.

$\%$ y data

y $=$ linspace$(-1,1)$;

$\%$ x data

x $=$ y $+$ cos$($y$)$;
