Part 3: Tips and tricks

π‘ Always ensure that the angle you input into the SIN function is in radians. If you have the angle in degrees, use the `RADIANS` function to convert it.

π‘ The SIN function can return values between -1 and 1. If you get values outside this range, recheck your input.

π‘ Combining the SIN function with other trigonometric functions like COS or TAN can provide more comprehensive insights into your data.

π‘ Remember that the SIN function can be handy in engineering, architecture, and physics, where angle measurements are crucial.

π‘ For more accurate results, especially in business scenarios, ensure your data is up-to-date and accurate before applying the SIN function.
