TAN (Function) [Conforms to SLIM]

Function

Obtains a tangent.

Format

TAN (<Expression>)

Explanation

This statement obtains the tangent value of the value in <Expression>.

Designate the unit of <Expression> in degrees.

If <Expression> includes a double precision real numeral, the obtained value

becomes double precision. Otherwise, a single precision value is obtained.

If an argument is entered in radians, add RAD after the constant.

Explanation: The TAN function receives an angle as an argument and

returns the ratio of 2 sides of a right triangle including

the right angle. The 2 sides mentioned here include the

right angle. The ratio of the 2 sides is the value of the

opposite side length from the obtained angle divided by

the adjacent side (base, or side adjacent to the obtained

angle) length. To convert degrees to radians, multiply

the degrees by π

ππ

π/180. To convert radians to degrees,

multiply the radians by 180/π

Example

DEFSNG lf1, lf2, lf3, lf4, lf5

lf1 = TAN(0.78525) 'Assigns the tangent value of 0.78525 to lf1.

lf2 = TAN(lf4) 'Assigns the tangent value of lf4 to lf2.

lf3 = TAN(45) * lf5 'Assigns the tangent value of 45 degrees multiplied by

'lf5 to lf3.
