280 Chapter 12 Dictionary of Functions

The T function retrieves text from a cell. If the cell doesn’t contain a string, T returns an

empty string.

T(cell)

Â cell: A reference to the cell from which you want to retrieve text.

Notes

This function is included so you can use spreadsheets created with older spreadsheet

applications that might use it.

TAN

The TAN function calculates the tangent of an angle, the ratio of the sine to the cosine.

TAN(radian-angle)

Â radian-angle: An angle in radians.

Notes

If you measure angles in degrees instead of radians, you can use the RADIANS function

to convert degrees to radians for the TAN function.

If you want to express radians as a multiple of pi, you can use the PI() function to

provide a value for pi.

Examples

If cell A1 contains "text" and cell B1 is empty:

T(A1) returns "text" and T(B1) returns nothing.

Examples

TAN(1) returns 1.557407725, the tangent of 1 radian (approximately 57.3 degrees).

TAN(RADIANS(45)) returns 1, the tangent of a 45-degree angle.

TAN(3*PI()/4) returns -1.
