Step wise Equation Solving - mathemagic12 - 07-05-2015 08:56 PM
I was writing a program to obtain the results of a linear quadratic equation and i used the jhplot.math.Numeric class to compute the results. I was wondering if i could
a) solve quadratic equation in a step by step fashion storing intermediate results.
for example :
x2-4x+3=0
x2-3x-x+3=0
x(x-3)-1(x-3)=0
(x-1)(x-3)=0
x=1 and x=3
b) plot the quadratic equation as a graph in 2d space.
I am using the data melt one jar file to write the program in java and am a newbie.
Any help in this regard would be much appreciated.
thanks.

Hello,
I'm not sure about intermediate steps, but to solve and
[/code][/php]plot quadratic equations are easy:
Code:
from jhplot.math.Numeric import *
b=solveQuadratic(1, 2, -1) #a=1, b=2, c=-1
print b.tolist()
from jhplot import *
c=HPlot()
c.visible()
c.setAutoRange()
f=F1D("x**2+2*x-1",-5,5)
c.draw(f)Also, check Apache common math included into the package
best, Sergei
