Question 1183482
a. The area between the upper curve of the parametric equations {{{x = 3t^2 - 6t}}}, {{{y = t^4 - 2t^3 - 2t^2 - 2t + 5}}} and the x-axis
 (i.e., between the point (−3,0) and (9,8)) is given by 


{{{A = 6 *int((t^5 - 3t^4+7t - 5), dt, 1,-1) = 56/5}}}.

b.  The expression for the arc length from  from the point (9,8) to the point (24,93) is given by


{{{int(sqrt(16t^6-48t^5+4t^4+32t^3 +76t^2-56t+40), dt, 3,4)}}}
