Question

Consider the vector FIeld
F(x; y) =(sin(y).*cosx+1./2)i+ (sinxcosy+1./5)j This vector eld is conservative. Find a potential function  for F and plot as Figure 1 the
level curves for  which pass through the 9 points (k; L) where (k; L) = 1; 2; 3. On the same graph,
plot the vector FIeld F at those 9 points. Use axis ranges of [0; 4] on the x- and y-axes. I am confused how to approach this. Any tips or help? The program i am using is matlab
