Find r, T, N, and B at the given value of t. Then find the equations for the osculating, normal, and rectifying planes at that value of t. r(t) = (cos t)i + (sin t)j - 2k, t= = D i t Di + ( ) K (Type exact answers, using radicals as needed.) (Type exact answers, using radicals as needed.) 2 (Type exact answers, using radicals as needed.) B (Type exact answers, using radicals as needed.) The osculating plane at t = is "Type an equation.) The normal plane at t = = is (Type an equation.)
