Evaluate the integral. x/3 -/3 [(1+2 cos t)i + (6 sin tj + +2 cos t)i + (6 sin t)) + ( sec t) k] dt = /3 1/3 [(1+2 [(1 + 2 cos t)i + (6 sin t)) + ( sec t) k] dt = i + + O* (Type exact answers.) Evaluate the integral. x/3 -/3 [(1+2 cos t)i + (6 sin tj + +2 cos t)i + (6 sin t)) + ( sec t) k] dt = /3 1/3 [(1+2 [(1 + 2 cos t)i + (6 sin t)) + ( sec t) k] dt = i + + O* (Type exact answers.)
