How do I emove the case to change the battery?

Remove slide cover. Place calculator face down. Using a small Phillips screwdriver, remove screws from back case. Install new batteries positive side up, as shown on diagram inside case.

Will it provide inverse calculations?

Yes, it has inverses for most of the functions it provides. Press the green [2nd] key to access the functions printed in light green above the other keys, e.g. [2nd] [sin] for sin-1, the inverse sine function.

is there memory function?

One of the reasons I have been using this model calculator for the last 20+ years is because it DOES have a memory. You can store up to 3 values by simply pressing STO and then 1, 2, or 3. To Reclaim the stored value press RCL and then 1, 2, or 3.

Does this new ti have a hard slip cover like my old 1995 ti-30x has? I keep mine in my toolbox next my hammer & the hard cover protects the keypad.

Yes it does! As well as some instructions in the hard cover slip.

Just a great calculator.

I have a bunch of these in different places just lying about for when I need a calculator. Just stop to ponder that you can drop ten bucks and have more computing power than was available to anyone, and I do mean anyone, in the 70s and 80s. I bought my first calculator in the mid 70s. It costs a fortune and could add, subtract, divide and multiply .. that was it. The your smart phone has more computing power than mainframes in the 70s and 80s. Really good calculator for ten bucks. I regularly use many of the scientific functions and the calculator is pretty ease to use. I think it would be just great for high school and early college math classes.
