Math

In Google Sheets, the TAN function is used to calculate the tangent of an angle given in radians. The function syntax is as follows:

TAN(angle)

"angle" is the angle in radians for which you want to calculate the tangent. Here's an example to demonstrate how to use the TAN function:

Let's say you have an angle of 45 degrees that you want to find the tangent of. In cell A1, you can use the formula:

=TAN(RADIANS(45))

The RADIANS function is used to convert the angle from degrees to radians since the TAN function expects the angle to be in radians. The RADIANS function converts the angle to 0.7853981634 radians (approximately).

The TAN function will then calculate the tangent of the angle and return the result. In this case, the result would be 1 (approximately).
