Consider a [b]continuous[/b] function f(x) defined on the interval [0,[b]a[/b]]. [br][br]Things to try:[br][br]1. Change the function f(x). [br] [b]Examples: [br][/b] 1. f(x)=sin(x^2-1)[br] 2. f(x)=1/(x+1) [br] 3. f(x)=4*sqrt(1-x^2)[br][br]2. Change the value of [b]a[/b]. [br][br]3. Drag Slider [b]n[/b] to approximate the area.
