The calculators are divided into several groups, the description is available if you move your mouse on the name of each group (the first row of the menu).
Definite integral in geometry
Formulation of the problem Curves on boundary:
Upper bound: f(x) =
Lower bound: g(x) =

Bounds on x axis: (you can try to find the intercepts of both curves by choosing "intercepts" in parameters for computation)
  lower bound=           upper bound =
Parameters Action:
          Find area between two curves and draw graph.
          Find volume of solid of revolution and draw graph
               preview solid of revolution  show colors, no mesh  hide invisible parts
          Find intercepts of curves

Bounds for the picture (decimal numbers)
xmin =     xmax =
ymin =      ymax =
