hello. I need help with this.

(1 point) Evaluate the line integral by following the given steps. (4x, 2y, zy) . dr Cis given by the vector function r(t) = (cos(t) , sin(t), at), t E o, 6 The differential dr can be found by differentiating r(): dr = I dt, Express the line integral in terms of t (4x, 2y, zy) . dr = dt. where E Evaluate the integral (4x, 2y, xy) . dr = E
