Here is a small TI 83/83+ program I wrote for adding vectors. It was designed to check your answers, not as a substitute for thought.
It will not show work, and you will need a firm understanding of vectors to use it properly.
:ClrHome
:Radian
:re^/theta/i
:Prompt A,B,C,D
:Ae^(B/degree/i)+Ce^(D/degee/i->E
:Degree
:Disp E, angle(E
As for the prompts, enter the magnitude of Vector 1 for A, the angular measure of Vector 1 for B,
the magnitude of Vector 2 for C, and the angular measure of Vector 2 for D. The first output (E) shows the magnitude of the resultant vector. The second output (angle(e)) is the angular measure of the resultant.
NOTES:
- O degrees is East, 90 is North, 180 is West, 270 is South, -90 is South, etc
- to subtract vectors, make one of the inputted vector magnitudes (not angle) negative
NOTES FOR TYPING IN:
- Radian, Degree, and re^/theta/i instructions can be pasted from the Mode menu
- e^( is [2nd][LN]
- i is the imaginary symbol ([2nd][.])
- /degree/ is the degree symbol ([2nd][angle][1]) |

| Shouldn't that be Disp E/(e^(angle(E)i)),angle(E ? |

Since you're in re^[font="SYMBOL"]qi, you could do
Disp real(E),imag(E)
EDIT: I meant to say "Disp abs(E),angle(E)" what I said would resolve the vector into its rectangular components.

Quote: Shouldn't that be Disp E/(e^(angle(E)i)),angle(E ?
Yes, that would make the display clearer, but I just ignore the e^(part).
I tried to keep it as umcomplicated as possible, in case I want to use it in an exam (I have it memorized).
Quote: Since you're in re^qi, you could do

Yes.
You could also use:
:ClrHome
:Radian
:re^/theta/i
:Prompt A,B,C,D
:Ae^(B/degree/i)+Ce^(D/degee/i
:Degree
:Disp Ans, angle(Ans
to save a byte, but some find it harder to follow, and you don't have the vector in a variable. |
