# Question:Calculating the area above and below a graph

## Question:Calculating the area above and below a graph

Maple

Hi, I have plotted an implicit 3d plot of an extensive equation into maple, but the particular equation represents a treshold, as it is calculated as the difference between two equations. Which means that everything below the graph represents the case were equation one is bigger than equation two and everything above the graph the opposite. Now by changing the parameters held constant before, I would like to make clear what happens to the chance that one equation is bigger than the other. So to come to the point, is it possible to calculate the surface below and above a certain graph? and how do you do that? I think my story maybe a little unclear so below the input:

Hope you can help! Thank you.

> plot:implicitplot3d(vergelijking, c=0..1,c2h=0..1,t=0..1,axes=normal);

So this was my input, hope somebody will and can help?
