TAN (Angle)
Returns the tangent of an angle.
Syntax
x = TAN (Angle)
Remarks
The angle argument can be any valid numeric expression measured in radians.
TAN takes an angle and returns the ratio of two sides of a right triangle. The
ratio is the length of the side opposite an angle divided by the length of the side
adjacent to the angle.
To convert degrees to radians, multiply degrees by
π/180. To convert radians
to degrees, multiply radians by 180/
π.
TAN Function Example
The example uses TAN to calculate the tangent of an angle from a Volt(1)
input.
Dim Degrees, Pi, Radians, Ans 'Declare variables.
Pi = 4 * Atn(1) 'Calculate Pi.
Degrees = Volt(1) 'Get user input.
Radians = Degrees * (Pi / 180) 'Convert to radians.
Ans = TAN(Radians) ‘The Tangent of Degrees.
TANH (Expr)
The TANH function returns the hyperbolic tangent of an expression or value.
Syntax
x = TANH (Expr)
Remarks
The TANH function returns the hyperbolic tangent [ tanh(x) = sinh(x)/cosh(h) ]
for the value defined in Expr.
TANH Function Example
The example uses TANH to calculate the hyperbolic tangent of a voltage input.
Public Volt1, Ans 'Declare variables.
VoltDiff(Volt1,1,mV5000,1,True,100,500,1,0)
'Returns voltage on Channel(1) to Volt(1)
Ans = TANH( Volt1 ) 'The Hyperbolic Tangent of Volt1.
