To get the inverse log function, press 2ND and then choose 10x. (Above LOG.)
To get the inverse of a natural log function, press 2ND and then choose ex. (Above LN.)
No. I believe TI83+ and TI84 do use an operating system.
multiplicative inverse of 1 plus i is 1 minus i
Yes. The TI83 has several applications that can be downloaded onto the TI83, mainly those made by Texas Instruments. Also, you can write your own software.
the inverse of x+3
It depends on whether you mean additive inverse or multiplicative inverse.
The additive inverse is x5 + 2x - 2.
The inverse of a number is 1 divided by that number. So the inverse of x3 + 1 is 1/(x3 + 1).
There are online graphing calculators. However, as of writing, there is no emulated TI83 that runs within your browser. On the other hand, if you have a Ti83, it is possible to copy its ROM to run an emulated TI83 on your desktop via one of many emulators.
No, f(x) is not the inverse of f(x).
The multiplicative inverse of 3+2x is 1/(3+2x).
No, it really depends on the college. Some colleges don't allow any calculators for their math classes. Everything that can be done on a TI83 can be done with the human brain, so some professors make tests with easier computations so that you don't have to use a TI83
Press "ALPHA", then press "."
