Math 202 Final Exam Fall,2008 Part I Do all parts of the following six problems. (1) Compute the derivative dy dx for each of the following (18 points) : (a) y = ln( 1 x + 1 ) . (b) y = arcsin( x ); (c) y = sin( x ) x + sin( x ); (2) Compute each of the following integrals(24 points): (a) Z x 3 + 2 x 3 - x dx ; (b) Z tan( x ) sec 4 ( x ) dx ; (c) Z p 4 - x 2 dx ; (d) Z 1 0 arctan( x ) dx. (3) Compute each of the following limits (10 points): (a) Lim x →∞ x e - x ; (b) Lim x 1 + x 1 / ( x - 1) . (4) The region R in first quadrant of the xy plane is bounded by the curves y = sin( πx ) and y = 2 x . Set up two integrals (method of washers and method of shells) for the volume of the solid obtained by rotating R around the line y = 2. Do not compute the value of the integrals(10 points) (5) Sketch the curve given by the equation r = 3+sin( θ ) in polar coordinates, labeling the x and y intercepts, and compute the area it encloses.
