Graphing Calculator

Capable of order of operations

multiple graphs using OpenGl

formula creator

example input for graphing

2*x^2

1/x

x^.5

-x^2

x^3

Note: formula and graphing input is extremely picky and not user friendly yet. Improper input will crash

2x^2 will not work but 2*x^2 will

a negative and then bracket may cause incorrect answer or app crash eg (5*3)-(1+1)

power sign does not have bracket support as of yet eg 2^(1+1) will not work

TODO

Graphing

-fix vertices array to calculate how many vertices needed(this will also fix adding too many graphs crash)

-fix gap in between vertices for some graphs like 1/X or when graphs extend further out like in X^2

-basic line graph y = x does not work. no output but y = 2*X + 1 works (I think has to do with operators)

-add numbers to grid (user definable interval)

-implement 3d graphing 2 issues for now, computation time and function input standard for user

-when clicking on function from list view options dialog pops up where user can change color of graph etc for each individual graph

-pinch zoom and rotate

Formulas

-user defined categories to help organize eg(physics,trig,math,stats)

-multiline formula list view

-share dialog window

-implement bluetooth to share formula strings

Error check input

-make impossible for user to input improper input eliminating syntax errors when calculating eg(2+5**3) in this case do not allow two operators in row

corner case crashes

find and delete deprecated code

Optimize

-save postfix instead of initial function instead of converting to postfix each time calculation occurs

GUI Stuff

-RPN notation

-allow 2x + 3 as input

-expand output screen to show past equations and answers

-tactile feedback(vibration)

-delete clear button and make outfield onclick clear field

-backspace key and selection for field

-design for all device sizes

-superscript output when power symbol is involved '^'

-design minimalistic layout that has trig functions, square root, Logs, Ln, !,pie,ln,log etc

-quick memory buttons for constants

-high res Logo design
