Question

Find a vector parametric equation r⃗(t) for the line through the points P=(1,0,−2) and Q=(1,5,1) for each of the given conditions on the parameter t. (a) If r⃗ (0)=<1,0,−2> and r⃗ (4)=<1,5,1>, then r⃗ (t)=

anonymous · Answer

r(t) = <1,0,-2>+t<1,5,3>.....i type that in and webwork says no. why? that's the answer....lost....

dan815 · Answer

cause r(4) is not satisfied

dan815 · Answer

r(t) = <1,0,-2>+t/4<1,5,3>

anonymous · Answer

@dan815 , why did you have to divide t by 4?  the next one has r(7) and r(11).
