Drawing canvas

two-dimensional drawing canvas which display a curve made by inputted formula expression[Y=f(X)]

Total num. of array elements

Total number of array[x, y] which is determined by performing calculation of formula expression[Y=f(X)]

Status field

A region which show the status of processing, error, exception, etc.

Coordinates [X]

X value which the point device indicate in drawing canvas[ⓐ]

Coordinates [Y]

Y value which the point device indicate in drawing canvas[ⓐ]

Result Output fie

A result arrays[x, y] which is determined through calculation of formula expression[Y=F(X)]

Function input field

As a user input field, it is permitted that all of the formula expression which satisfy necessary condition as a function[Y=F(X)]

Boundary [x]

Minimum and Maximum values of X-axis.

Boundary [y]

Minimum and Maximum values of Y-axis

Origin

X and Y values of Origin of this coordinate. The element of origin should be located between min and max value of X-axis and Y-axis respectively
