i have written a few to make life a little bit easyer
Simple for finding a cube volume
PROGRAM: CUBE
Prompt L,W,H
LWH->V
Disp "Volume Is",V
Disp "Made By James F."
For changing celcius to ferenheight (sp?)
PROGRAM: CELCIUS
Prompt C
C*1.8+32->F
Disp C,
Disp "IN FERENHEIGHT"
Disp "Is",F
Disp "Made By James F."
Volume of a Cone
PROGRAM: CONE
Prompt B,H
BH/3->V
Disp "the volume of the cone is",V
Disp "Made by James F."
Volume of a Cylinder
PROGRAM: CONE
Prompt R,H
(pi symbol)R^2H->V
Disp "Volume of this cone is",V
Disp Made By James F.
This program displays your current age in dog years
PROGRAM: DOGYEARS
Prompt A
A*7->D
Disp "You are",D
Disp "In Dog Years"
Disp "Made By James F."
This changes Ferenheight to celcuis
PROGRAM: FERENHEIGHT
Prompt F
(F-32)*0.555->C
Disp ,F
Disp "In Celcuis Is",C
Disp "Made By James F."
This uses pythagorus therom
PROGRAM : PYTHAG
Prompt A,B
A^2+B^2->C
(square root)C->D
Disp "Side A Is",A
Disp "Side B Is",B
Disp "So Side C Must Be",C
Disp "Made By James F."
The Volume of A sphere
PROGRAM: SPHERE
Prompt R
4(pi)R^3/3->V
Disp "The Volume of this sphere is",V
Disp "Made By James F."

here are some ones that i shall soon enter because i have physics next term
simple program for density were "M" is mass and "V" is Volume
PROGRAM

ENSITY
Prompt M,V
M/V->D
Disp "The density of this object is",D
Disp "Made By James F."
Distance program were "V" (m/s) is average velocity and "T" (s) is time
PROGRAM: DISTANCE
Prompt V,T
V*T->D
Disp "The Distance of this object is",D
Disp "Made By James F."
This is an acceleration program were "V" is final velocity and "W" is the intial velocity and "T" is the time and "A" is the acceleration
PROGRAM: ACCELERATION
Prompt V,W,T
V-W/T->A
Disp "the acceleration is",A
Disp "Made By James F."
This is Distance B it is fairly simple look in the second line there's your formula
"V"=initail velocity "T"=Time "A"=Acceleration
PROGRAM: DISTANCEB
Prompt V,T,A
V*T+1/2*A*T^2->D
Disp "the distance is",D
Disp "Made By James F."
Simple net force program f=m*a
PROGRAM: DISTANCEB
Prompt M,A
M*A->F
Disp "The Net Force Is",F
Disp "Made By James F."
and there are billions more that i am going to be making but thats all im writing for now if you can please post the scripts you have made for your calculator to make your life easiyer
