Solve the initial value problem for 7(1). (0)-7-(2+2) 7+27 +4% 7(0) = 37+87(0) = 7 47 + k d(1) For the curve parametrized below, at the point (1,0,0), find the unit tangent vector, principle unit normal vector, and curvature. 7(t) = (cost)i + (sint)] + (In(cost)) (-1, 1) Write a at the point (4,0,2) in the form a = a +aNN without finding 7 or . 7(1) = (47)7 + (Int)] + (21) 1>0
