Match the description of the curve with the integral that describes its are 1. Find the arclength from t=1 to t=4 of the curve described by the following parametric equations. V (12t + 4)2 + (36t2) 2dt x = 6t2 + 4t y = 12+3 - 5 2. Find the arclength from V (2 cos(t) )2 + (-2 sin(t))2dt t=1 to t=4 of the curve given by y=f(t). f(z) = +3 - 3t+1 1 + (3t2 - 3)2dt 3. Letting t = 0, find the arclength from t=1 to t=4 of the polar curve given by: r = 2 cos(t)
