Area calculation activity
One accesses this activity with the item "Area calculation" from the menu in "Scholar".
One enters a function and the interval endpoints a
and
b
. One bounds the intégral of this function defined between
a
and b
by the method of rectangles (Riemann sums)
. La function must be positive and monotic between the interval endpoints.
The function must be entered in a form involving the variable x. Functions defined in Scilab may be used in this expression. For example: x^2, 1/x, f(x), f(x^2)*g(x) etc.
The slide varies the number of rectangles. The routine displays upper and lower bounds for the integral (using upper rectangles and lower rectangles).
