Calculators Not getting the right answers for sine, cosine and tangent with TI-89

AI Thread Summary
Issues with obtaining correct answers for sine, cosine, and tangent functions often stem from whether the calculator is set to radians or degrees. To check the setting on a calculator, access the F2 menu and look for the options labeled "radians" and "degrees." Highlight the desired option and press enter to select it. Ensuring the correct mode is crucial for accurate trigonometric calculations.

Last night I had four docs with a red circle, one with blue. When I closed the blue and opened it again it was red. Today I have 3...
