# How do I change a Math Z Surface's x and y bounds?

I am new to blender and I am trying to make a 3D model of an equation that I came up with. When I create a math Z surface with the Extra Objects Add-on, I cannot seem to change the bounds of x and y. I need them to be both from -5 to 5. The equation I am trying to graph is found below:

z = (169/2048)*(y*cos(x))**2 - (1/16)*(x*sin((1/4)*y))**2 + fabs((15/32)*x)+cos(y) [-5 <= x <= 5] [-5 <= y <= 5]


Here is what blender is outputting:

And here is an example of what it should output:

Is there a way for me to change the ranges of x and y? Is there a different problem? I have tried changing the scale and dimensions but they both just stretch the already incorrect graph. I have also tried looking on the blender docs but I cannot find any information about this.

Thanks in advance for helping me out!
