- select and move (arrows/mouse) the green slider

- check the boxes to see the tangent and the derivatives

- for better view you can move (mouse) the labels

- if you want to reset the sketch press the reload button



  to repeat the activity using another function:

- type (en) the formula f(x)=... in the input field (Εισαγωγή:)
  and press enter.  (don't forget f(x)=)

- use brackets to specify the order of operations


       to take: sinx, cosx, tanx, ex, logx, lnx

           type: sin(x), cos(x), tan(x), exp(x), log(x), ln(x)


       to take: a fraction, xn, |x|, square or cube root of x

           type: /, x^n, abs(x), sqrt(x), cbrt(x)
