To: Shareware Distributors of KURV+ for Windows
I am enclosing the latest upgrade to KURV+ for Windows (version 2.1):
1. The maximum file size has been increased five fold; KURV+ can now
process files containing up to 500 data pairs.
2. A nasty bug, which can produce incorrect equation coefficients when
very large numbers are used, has been eliminated.
REVIEW OF FEATURES
KURV+ is comprised of two mathematical modules: a Curve Fitting module
and a Geometry/Trigonometry module.
Curve Fitting Module:
X,Y data points supplied by the user are processed to determine the
coefficients for 28 mathematical equations (including third, fourth and
fifth order polynomials). A built-in data editor allows the user to
create, edit, or import files for curve fitting. Changes to files, and
the resulting curve fit changes, can be rapidly made from KURV's master
control panel. Comparisons of calculated points with actual data points
are instantly available. The user can also forecast results for points
beyond the range of the input data. The comparisons and forecasts can
be displayed as graphs or as tables. All graphs and tables can be
printed via the Windows printer interface; they can also be copied to
the Windows clipboard for insertion into other Windows programs.
Geometry/Trigonometry Module:
This module will compute the area of nine plane geometrical figures
(circle, circular segment, circular sector, ellipse, parabola,
triangle, parallelogram, trapezoid, regular polygon) The surface area
and volume of seven three dimensional figures can also be computed
(sphere, spherical segment, spherical sector, ellipsoid, paraboloid,
cone, cylinder). The area of an irregular polygon, with up to 500
sides, can be calculated (great for determining floor space, acreage,
and lot area). Additionally, the parts of a triangle (unknown angles
and sides) can also be calculated.
REQUIREMENTS
KURV+ requires Windows 3.x; a hard disk or high density drive is
required for installation. A Windows SETUP program is included for ease
in installing KURV+. The file VBRUN200.DLL is also included. Two 360K
floppy disks are required for distribution of KURV+.
