Q1. Chose the correct answer: 1. One of the following vectors is parallel to the line whose equation is ( x-2=3, y-2==0) (a) = -i+2j-2k (b) = i +2j-k (c) V = −i + j −2k (d) v = 2i+2j+k 2. The line (x=21 +1,3 = 3+1, ż = −1+4) intersects the yz plane at the point: (a) (0,0,7) (b) (0,5/2,9/2) (c) (0,7/2,0) 3. The curvature of the curve x² + y² = 36, is equal (a) 36 (b) 6 (d) (7/2,7/2,7/2) (c) 1/6 (d) √6 4. Given (f(x, y) = tan' (y/x)), then af lay is equal x (a) x²+ y² (b) -x x² + 1/x (c) x² + y² (d) 1. One of the following vectors is parallel to the: (3. -7y+2 = 0) (a) v = 2i+7j (b) =-7i-3j (c) =7i+ j (d) V=7i+3j
