 Posted: 18 Feb 2004 05:38:45 pm    Post subject: 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])

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 Disp real(E),imag(E) 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.
