(10 pts) Let c : [ a,b ] → R 2 be a unit speed parametrization of the path segment sitting between (0 , 0) and (1 , 1) of the parabola y = x 2 . Evaluate ∫ b a f ( c ( t )) dt , where f ( x,y ) = √ x 2 + 3 y + 1. 2. (10 pts) A parametrization for the hyperboloid of one sheet is given by x = (cosh u )(cos θ ) , y = (cosh u )(sin θ ) , z = sinh u, where 0 ≤ θ &lt; 2 π and −∞ &lt; u &lt; ∞ . Find the tangent plane to this surface at the point ( x,y,z ) = (1 , 1 , 1). 3. (10 pts) For a vector field F ( x,y,z ) = y 3 i + (3 xy 2 − y 2 ) j and a simple path c ( t ) = (2 sin t, cos 3 t, 1 − cos 2 t ) (0 ≤ t ≤ π ), find the integral ∫ c F · d s . 4. (15 pts) Use Green’s Theorem to prove ∫ 2 π cos 2 n tdt = 2 n − 1 2 n ∫ 2 π cos 2 n − 2 tdt for any positive integer n ....
