5. Find the asymptotes of the curve (x-y) (x + 2y + 1) +x+y+1=0. OR Show that the radius of curvature for the curve r = a cos me is 6. Integrate any three: m a (m+1)r' m-1 cos xdx /4 sin 20d0 a) 4 (1 + sin x)(2 + sin x) sin+ + cos c) S Vcot xdx d) 1+cotx L 2 dx 7. Evaluate xdx by the method of summation. 5.
