Ted demonstrates how to use trigonometric functions in Excel, starting with setting up a spreadsheet with angles in degrees. He explains the importance of converting degrees to radians for Excel's trig functions and provides a formula for this conversion. Ted then shows how to apply sine, cosine, and tangent functions, highlighting the issue of undefined values when the cosine is zero. He encourages experimenting with other trig functions available in Excel, such as cosecant and hyperbolic functions.
