TAN

TAN(number)

Returns the tangent of a number.

number

The number you want the tangent of.

REMARKS

* For an illustrated example refer to the [[Trigonometric Functions]] page.
* The inverse of this function is the ATAN function.
* The tangent of a number is 1/COT.
* This function is periodic with a period of 2PI.
* The "number" is the angle in radians.
* If "number" is not numeric, then #VALUE! is returned. Example 14.
* If your argument is in degrees, multiply it by PI/180 to convert it to radians.
* If you want the result to be in degrees, multiply the result by 180/PI.
* You can use the ATAN function to return the arc-tangent. Example 15.
* You can use the COS function to return the cosine.
* You can use the SIN function to return the sine.
* You can use the DEGREES function to convert from radians to degrees.
* The equivalent VBA function is VBA.TAN
