20 Most Recent Texas Instruments TI-Nspire CX Graphing Calculat Questions & Answers

To transfer the operating system to the handheld, connect your handheld and computer with a USB Connection Cable and use TI-Nspire™ Teacher Software with TI-SmartView™ or TI?Nspire CX Student Software (Windows® / Mac®). This is the link that will download the OS (it's free) to your computer: http://tinyurl.com/nrkpy3e

It opens an explore type window. Under the TOOLS tab find Install OS. If it does not connect to the Internet, point the software to where you stored the downloaded OS.

How to find the mean and standard deviation of discrete random value...

Use the original charger. The charge process may seem rather long.

Better have it serviced by Texas Instruments.

Here it is. I hope it is clear enough.

Undo the screws on the back. At your own risk.

Recharge the battery and see what happens.. Could also be that the autodim feature is fixed to the lowest value (30 s).

That is a round-about way to solve cos(x)=0.543 by graphing. Use the inverse function of the cosine arccos or cos^-1 If cos(x)=0.543 then x=arccos(0.543) To graph a trigonometric function it is more natural to use the radian as the unit. However in geometry it is more common to use the degree. To solve an equation like x=arccos(0.543) where you want the answer to be degree, change the document settings to make the default angle unit the degree. Make the graphing angle unit the degree and set that as default by selecting Make Default and press Enter.

Sorry to hear that such calculator has been ruined by water damage, Let it dry thoroughly and try it again.

At first, in menu choose settings and set on Graphing Angle option to Radian. Then graph function. See captured image
