Define the equation cos(x) sin(y) = .25, by using
>f:= cos(x-y)*sin(y)=.25
Right click on the expression you get after defining f, and use the
“plots →plots builder” command to plot the curve. First plot the
curve with domain and range [-10,10] and use the grid [30, 30].
Then do the same, but using the grid [100, 100]. State what you
thinkthe “grid” does
