Hello again, thanks to everyone who has answered my questions.  It's difficult jumping into Maple starting with calculus 3, I wish I would've used it more in 1 and 2... BUT anyways, my question:

How do I get Maple to solve a vector equation given a time t?

For example, my two equations I want to solve are:

eq := r(t) = 2*t^2*_i+16*_j+(10*t-12)*_k

eq := r(t) = (20-6*t)*_i+4*t^2*_j+2*t^2*_k

Both solved at time t=2 ("when the airplanes collide").  I want these solved so I can use another Maple command to find the angle between the two vectors upon collision.  Does all this need to be done in steps or is there a more concise way?
