Sketch the vector field. 8 2 0 -2 0 y 0 2 0 -2 F(x, y) = (2, 2) = 2'

Can you please help me with this question and can you please do it step by step so I can follow along and understand it because I need to understand it

O (a) O (b) O () Question 2 1 pts The unit vector tangent to the curve r(t) =(1,41²,3t² ) is (a) (0,4/5,3/5). (b) (0,8t,61) . O (a) O () O (b) Question 3 1 pts The vectors T and N, when defined,

orthogonal to the vector y = (2)? You may want to go through the proof of When is the vector x = projecting y on x and the implications of (intuition behind) "orthogonality".
