Hi all. I have the following equation describing the isoline in the graph I will attach below.

P=((1025*9.81^2)/(64*pi))*(Hs^2*Te*tanh(k*d))*(1+(2*k*d)/(sinh(2*k*d)))

I only need to plot those isolines, described by the equation above. (ignore the boxes inside the graph, I am only interested in those isolines)

Maybe the starting point is to compute all the Te (x values) and Hs (y values) whose combination will always give me a fixed result i.e 2,5,10,20,50?

Thanks

Read about linspace. With this create x, y values i.e. .
Make x, y matrices by using meshgrid.
Substiture these values in the given formula. You have to use element by element operations. Read about them.
USe contour to plot.
