How do you use the pi key on TI-30xs?

Answer 1

To use the pi key on the TI-30XS calculator, simply press the "2nd" button followed by the "π" key, which is often labeled as "π" above the division key. This will insert the value of pi (approximately 3.14159) into your calculation. You can then continue with your calculations as needed. Make sure to close any parentheses if you're using pi in a larger expression.
