Let r(t)=ti+%t2j+t2k a) Find the function T(t) b) Find the equations for the tangent line at the point (2, 2, 4). c) Find the equations for the normal line at the point (2, 2,4). d) What is the normal plane to the curve at the point (2, 2,4). e) Graph the space curve, point, tangent line, normal line and normal plane in CalcP/ot3D. Print a good view showing all five in the same plot. You can use multiple screen captures. (2,2,4)
