This depends on what function, and what TI calculator.

To find the zeros of a function using a TI-30X calculator, first, enter the function into the calculator using the appropriate mode (usually in "function" mode). Then, use the "Table" feature to generate values of the function. Look for where the function changes signs, indicating a zero. You can then estimate the zero by narrowing down the interval around the point where the sign change occurs. Note that the TI-30X does not have a built-in root-finding feature, so you might need to use a graphing calculator for more precise results.
To exit Press to Test mode on a TI-Nspire CX calculator, simply restart the device. Hold down the "On" button for a few seconds until the calculator powers off, then turn it back on. If the calculator is still in Press to Test mode, you may need to connect it to a computer with the TI-Nspire software and use the "Reset" function to restore normal operation.

To find the zeros of a function using a TI-84 calculator, first enter the function into the Y= editor. Then, access the "Calc" menu by pressing the "2nd" button followed by "Trace." Select the "zero" option, and the calculator will prompt you to set a left bound and a right bound around the zero. After entering these bounds, the calculator will calculate and display the zero of the function.

There is not cos2 button on a TI-83 plus. You will need to enter the cosine function and then square it. (Press the x2 button to get the squared function.) To type cos2(90) on a TI-83 plus, for example, type: cos(90)2

The Titanium version of the TI-89 is a better version of the generic TI-89. It boasts more RAM, a more robust math function library, and a mini-USB port.
