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
