I have a few small programs:

QD: (Quadratic Formula) - Credit goes to the document "1 Minute Marvels" by Wldoek Mier-Jedrzejowicz and Richard Nelson (They have this program named 'quad')

Input:

3: A

2: B

1: C

Output:

2: root 1

1: root 2

<< 3 PICK / SWAP ROT -2 * / DUP SQ ROT - SQRT + LASTARG - >>

SQRT: Square Root

Law of Sines:

sin(F1)/S1 = sin(F2)/S2. Apply this to any of the two sides and their corresponding angels. F represents theta which can be typed by pressing [alpha] [right shift] (F). (48S only?)

LAWSIN:

<< 'SIN(F1)/S1=SIN(F2)/S2' STEQ 30 MENU>>

Law of Cosines:

A^2=B^2+C^2-2BC cos F

LAWCOS:

<< 'SQ(A)=SQ(B)+SQ(C)-2*B*C*COS(F)' STEQ 30 MENU>>

30 MENU brings up the calculator's solver using whatever is stored in STEQ.

Hope this helps,

Eddie
