Calculate the tangent of an angle.

`TAN(number)`

- number - required argument, the angle in radians

`=TAN(PI()/4)`

The TAN function can take an angle in radians and return the tangent of that angle. For example, to return the tangent of 45 degrees, you would use the formula above. This formula will return the value 1.0.

`=TAN(60*PI()/180)`

The TAN function can also take an angle in degrees and return the tangent. To calculate the tangent of 60 degrees, use the formula above. This will return the same value as the previous example, 1.0.

The TAN function is used to calculate the tangent of an angle given in radians. It returns the tangent of the given angle as its result.

- The angle must be supplied in radians to get the tangent of an angle using the TAN function. It can also be used to calculate the tangent of a full rotation.
- The TAN function has asymptotes at the range [0,2Ï€].
- The TAN function can be equivalently defined using SIN and COS.

The TAN function is a mathematical tool that calculates the tangent of an angle. It takes a radian angle as input and produces the tangent of the angle as output.

The TAN function can be used to calculate the tangent of an angle using PI()/180 or RADIANS. It can also be used to determine the ratio of a triangle's opposite side to its adjacent side and to calculate the length of a side or angle in a right triangle.

The TAN function is different from other functions as it calculates the tangent of an angle and requires a radian angle as input. Other functions may calculate the sine or cosine of an angle or require a different type of input.

To use the TAN function, you need to know the angle in radians that you want to calculate the tangent of. You can also use PI()/180 or RADIANS to calculate the tangent of an angle.
