@Carl Love Thank you so much I used it on another two functions and it worked perfectly.
Now i'm trying to plot another function, which is basically an approximate solution of a PDE that I found using a procedure in Maple (the solution is too long), but the running is taking too much time (3hr now and it's still evaluating), is there another way to plot a complex function in real 3D space ? 
It doesn't have to be an animation (because I think that it's taking time due to the animation process, I don't know it's just an assumption)
As you said earlier that there are a lot of ways to plot such functions.
Thank you so much in advance.

@C_R Thank you so much

@Carl Love Thank you so much for your answer that's exactly what I was looking for.
