**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.
