5. Create an anonymous function for the following equation f(x,y)=sin(x)+cos(y) a) Create a function mesh plot b) Set the plot from part a as figure 1 and create a new plot with the same function mesh plot but this time change the line color to black, set linewidth to 0.5, and mesh density to 25 . Set this plot as figure 2 and verify the changes with both plots side by side such as it shows below
