Any ideas what this means?
f(x) = 1 / 3 sqrt(9 - x²)
IntegralBetween[f, x, a, b]
Try Integral() not IntegralBetween()
Integral(1 / 3 sqrt(9 - x²), 0, 2.9)
This is the input i typed - the engine changed the command I am not intend to use Intergralbetween.
but I know what the command is doing, yet
I started with Integral( <Funktion>, <Variable> ) adding the limits.. Using a derivation variable causing a confusion...
> Using a derivation variable
That's not supported in the Algebra View (it changes to IntegralBetween() as you've noticed)
