Funct1.zip contains all nonintrinsic functions for QB v4.5 and is PD 2002.

Intrinsic trigonometric functions (included functions) are:

Cos(x), Sin(x), Tan(x), Atn(x), and are supplemented with:

Exp(x), Sqr(x), Sgn(x), Log(x).

The extended nonintrinsic functions which can be calculated using the
standard intrinsic functions are (in grouped order):

Sec(x)   - Secant
Cosec(x) - Cosecant
Cotan(x) - Cotangent

Arcsin(x) - Inverse Sine
Arccos(x) - Inverse Cosine

Arcsec(x)   - Inverse Secant
Arccosec(x) - Inverse Cosecant
Arccotan(x) - Inverse Cotangent

HSin(x) - Hyperbolic Sine
HCos(x) - Hyperbolic Cosine
HTan(x) - Hyperbolic Tangent

HSec(x)   - Hyperbolic Secant
HCosec(x) - Hyperbolic Cosecant
HCotan(x) - Hyperbolic Cotangent

HArcsin(x) - Inverse Hyperbolic Sine
HArccos(x) - Inverse Hyperbolic Cosine
HArctan(x) - Inverse Hyperbolic Tangent

HArcsec(x)   - Inverse Hyperbolic Secant
HArccosec(x) - Inverse Hyperbolic Cosecant
HArccotan(x) - Inverse Hyperbolic Cotangent

And additional functions are:

RadToDeg(x) - Convert Radians to Degrees
DegToRad(x) - Convert Degrees to Radians
Hypotenuse(x,y) - Calculate right triangle side

And additional constants:

PI (3.141), E (2.718)

'The numeric-expression can be of any numeric type.
'
'ATN is evaluated by default in single precision. If numeric-expression is
'a double-precision value, ATN is evaluated in double precision.
'
'The result is given in radians and is in the range -/2 to /2 radians,
'where  = 3.141593. /2 radians equals 90 degrees.
'
'You can convert an angle measurement from degrees to radians by
'multiplying the degrees by /180, where  = 3.141593.
'
'To convert a radian value to degrees, multiply it by 57.2958.
