## Draw graph

f(x) = : function to draw the graph or integrate.

## input example

2x -> 2*x sin4x -> sin(4*x) e^x -> exp(x) x^y -> pow(x, y) √x -> sqrt(x) π -> pi e -> e

## Option

You don't need to change these parameters.

: change by 1px [/px]: calculate frequency [px/times]

: absolute position of the x-axis [px]

: absolute position of the y-axis [px]

## Integrate

- I = ∫[a, b] f(x) dx
- a =
- b =
- dx = 1/
- I = 0
