I have entered the following equations into Wolfram and it seems to understand them. I'd like to solve for t in terms of the other scalars:
A={ax,ay}; B={bx,by}; C={cx,cy};
B'=(A+C)/2+t*(B-(A+C)/2);
d=(A-B').(C-B')/(Norm[A-B']*Norm[C-B']
)
I've tried variations on the Solve[] command but I am not sure how to express this. I'm also curious as to why Wolfram always says that variable C is protected in the above.
thanks, Pat
