okay so the question i have to answer is "write a maple function that computes the area of a triangle in the plane from the coordinates of the vertices"
ive gotten this far
triangle(ABC, [point(A, 0, 0), point(B, 2, 0), point(C, 1, 3)]);
but how can i write so when you type say AA([[0,0],[10,10],[10,0]]) it returns 50? (AA being the function name)
Thanks in advance to whoever helps.
