The Answer of Find the coordinates of the point where the line tangent to the curve $\vec { r } ( t ) = t \vec { i } + t ^ { 2 } \vec { j } + t ^ { 3 } \vec { k }$ at the point (4, 16, 64)crosses the xy-plane.

Find the Coordinates of the Point Where the Line Tangent r⃗(t)=ti⃗+t2j⃗+t3k⃗\vec { r } ( t ) = t \vec { i } + t ^ { 2 } \vec { j } + t ^ { 3 } \vec { k }r(t)=ti+t2j​+t3k
