(1) Find a vector equation for the curve of intersection between the surfaces y2−x2=9 and 2x−3y−z=12. Hint: cos2(t)+sin2(t)=1 and sec2(t)−tan2(t)=1. (2) If a particle has an acceleration given by ⟨6sin(3t),4t,2e−2t⟩, an initial position of ⟨0,0,1⟩ at t=0, and an initial velocity ⟨1,1,0⟩, then find the speed of the particle when t=2. Find an exact expression and then approximate the speed accurate to 3 decimal digits.
