Eigenpicture (11/17/2003)

This program draws an eigenpicture using the transition
matrix composed of row vectors A1 and A2.


:Radian:-2→xMin:2→xMax:-2→yMin:2→yMax:ZSqr
:[2,1]→A1
:[0,1]→A2
:For(D,0,360,10)
:D*pi/180→R
:cos R→I1
:sin R→I2
:[cos R,sin R]→I
:dot(A1,I)→E1
:dot(A2,I)→E2
:Line(0,0,I1,I2)
:Line(I1,I2,I1+E1,I2+E2)
:End

 

 

Volume: Parallelpiped

This Program calculates the volume of a parallelpiped
with vectors A, B, and C that represent the three edges
with a common vertex.


:Input "Vector 1=",A
:Input "Vector 2=",B
:Input "Vector 3=",C
:dot(A,cross(B,C))→Ve
:norm (Ve)→Vo
:Disp Vo

 

 

The Quadratic Formula

This program evaluates the quadradtic formula for
the coefficients A, B, and C.


:Prompt A,B,C
:((-B)+√(B^2-4*A*C))/(2*A)→X
:((-B)-√(B^2-4*A*C))/(2*A)→Y
:Disp X,Y
