(a) Find the point of intersection of the tangent lines to the curve r(e) = (5 sin(at), 6 sin(æt), 4 cos(mt)) at the points where t = 0 and t = 0.5. (x, y, 2) = (b) Find both tangent lines. Illustrate by graphing the curve and both tangent lines. (The tangent lines will be plotted for -1 sus1. Select Update Graph to see your responses plotted on the screen. Select the Submit button to grade your responses.) tangent line att = 0 (x(u), y(u), z(u)) = tangent line att = 0.5 (r(u), y{u), z(u)) = Update Graph Student Response Response Description
