- Fill in the table and then sketch the vector field. y F(x, y) = -2 -2 -2 2 -2 -2 -2 3- -2- 2. /- 2.arrow_forwardLet r(t)=cos 2t i +sin 2t j + t k be a vector function. Which of the followings are true for this function? I. Tangent vector is constant at any point. II. Length of tangent vector at any point is constant. II. Tangent vector is (0,2,1) at the point (1,0,0). IV. Curvature at a point (a, b, 4а+b c) is 50 V. Arclength of the curve from a point (a, b, c) to a point (d, e, f) is given by V5dt O a. II, II, IV Ob. II, II, V O C. I, II, V Od.I, II, IVarrow_forwardFind the space curve represented by the intersection of the surfaces. Then represent the curve by a vector-valued function using the given parameter (Use technology to sketch) x2 + y? + z? = 10, x + y = 4 x = 2 + sin (t)arrow_forward
