Science Graphs is useful for
algebra, trigonometry,
calculus, physics, differential
equations and engineering. It can also be
used to graph up to 1,000 x-y data points from an ASCII file. In addition,
the software allows you to solve differential equations, graph color contour
curves of 2-dimensional data generated by equations and contour structured
data saved as text files. It has a number of features for displaying the
contour graph and the data grid.

Use the equation editor to enter and plot numerical solutions of
first order non-linear ordinary differential equations of the form
y'=G(x,y).

Use the equation editor to enter and plot numerical solutions of
second order non-linear ordinary differential equations of the form
y''=G(x,y,y').

Solutions of: y''= y, y''=-.4y'-y
and y''=-.8y'-y

Aerodynamics

The following figures show the use of Science Graphs for graphing
contours from arbitrary 2-Dimensional functions. Here, the application is
aerodynamics, but the software can be used to plot contours for equations
for any discipline.

Doublet Flow: 1/R*Sin(Th)

Circular Cylinder:-10*R*Sin(Th) +
1/R*Sin(Th)

Corner Flow: X*Y

Vortex Near Wall:
Ln((X^2+(Y-.502)^2/(X^2+(Y+.502)^2)))

3-Dimensional Surfaces
Science Graphs Plus can generate plots of 3-Dimensional surfaces entered
as equations or data. The following are graphs of the equation
Z=Cos(4*R).

Computational Fluid Dynamics (CFD)

Computation Fluid Dynamics

Import and plot contour data on a conforming structured grid.

Display various combinations of the grid and data.

Use the equation editor to plot contours or 2-D functions in (x,y)
or polar coordinates.
