I have a function P = f(a, b, c) = squareroot( a^2 + b^2 + ac + bc), where a, b, and c are in intervals. I want to draw a 3D or cubical type plot where a, b, and c will be on the x, y, and z axes. My aim is to visualize how the interval value of P changes with inputs a, b, and c.
Let a = (20..30), b= (3..4), and c = (100..200).
Please note that a, b, and c are not points in some range but are intervals.
Please let me know if any other information is required.
Thank you in advance.
