Cartesian
Previous  Top  Next

Normal Cartesian functions (y = ...) can be entered into FX Graph with or without the y=.

y = 3x - 7

OR

3x - 7

Normal Cartesian functions are the most supported type of in FX Graph. Cartesian functions are REQUIRED for some of FX Graph's features.

FX Graph will rearrange functions into normal Cartesian functions if possible.

For example:

3x2 + y = 3x + 2

will be internally rearranged by FX Graph into:

y = -3x2 + 3x + 2

and all features will be available.

In the diagram above, notice how we entered the function as 3x2 + y = 3x + 2 but FX Graph has rearranged the function when finding the integral.
