Such as 22=y+(100^2)/(2(22y)^2) this problem should have two solutions. My TI 36 pro only gets one.
Type solve again option on TI 36 pro.
Thats true, there is two solutions. See captured image below
SOURCE: solving multiple non-linear equations
Type it like this: solve( equation1 and equation2 and moreEquations, {list of variables to solve for})
Put all of your equations right after the opening parenthesis separated by the word and, then a comma, then within curly braces each variable you want to solve for each separated by a comma.
SOURCE: TI 89 when solving equations or integrating a message appears:
With the ALPHA keyboard, Type in the NewProb command and press ]ENTER] It resets the one-letter variables to their default status.
Alternatively, you can use the CATALOG of commands to launch the NewProb command.
Another way is
In HOME directory, press the [2nd][F1] to activate the F6 key. In the menu list, press 1:Clear a-z and ]ENTER].
If you have to use the variable x multiplied by a function (sin, cos, tan, log, etc) do not used implied multiplication: enter the [*] explicitly.
SOURCE: I just got the TI-Nspire.
You need the TINspire CAS (Computer Algebra System) to do symbolic manipulations. The Blue TINspire (with TI 84 keyboard) can only perform numerical computations.
If you use variables, the calculator will assign the numerical value stored in the variable.
