Evaluate the line integral∫cf⋅dr, where f(x, y,z)=xi−4yj−zkf and c is given by the vector function r(t)=⟨sint, cost, t⟩, 0≤t≤3π/2.

Can you me with this question? i'll reward *30 points i just need with this one question so that i could solve the others. * edit: i originally set up the question to reward 30 points, but for some reason i can only reward 15. if you don't get 30, then i'm sorry. i'm still kind of new to this site
