That is a better way and easier way and from practical point of view it is a quite feasible to simulate the waves close to reality. So, accordingly with this statement equation 3 can be represented as shown here, all the variables are already defined I cannot keep on redefining or keep on telling what all the variables by now you should be familiar and now half amplitude square also provided here. Now I can select the number of directional components as approximately 30 and number of frequency components.
