Question 1134168: I need help writing a 4x5 matrix,A1 = input ('A1 :?');
B1 = input ('B1 :?');
C1 = input ('C1 :?');
D1 = input ('D1 :?');
A2 = input ('A2 :?');
B2 = input ('B2 :?');
C2 = input ('C2 :?');
D2 = input ('D2 :?');
A3 = input ('A3 :?');
B3 = input ('B3 :?');
C3 = input ('C3 :?');
D3 = input ('D3 :?');

DET = ((A1)*(B2*C3 - C2*B3)) - ((B1)*(A2*C3 - C2*A3)) + ((C1)*(A2*B3 - B2*A3))
DETX = ((D1)*(B2*C3 - C2*B3)) - ((B1)*(D2*C3 - C2*D3)) + ((C1)*(D2*B3 - B2*D3))
DETY = ((A1)*(D2*C3 - C2*D3)) - ((D1)*(A2*C3 - C2*A3)) + ((C1)*(A2*D3 - D2*A3))
DETZ = ((A1)*(B2*D3 - D2*B3)) - ((B1)*(A2*D3 - D2*A3)) + ((D1)*(A2*B3 - B2*A3))
X = DETX/DET
Y = DETY/DET
Z = DETZ/DET
