QUESTION
Find the arc length of the curve represented by the parametric equations over the given interval:
- Find the arc length of the curve represented by the parametric equations over the given interval: x= 2(cos t + t sin t) and y= 2(sin t - t cos t), 0<_ t <_pi
- at what points on the curve x= 2t3, y= 1 + 4t - t2 does the tangent line have slope 1?
- find the exact are length of the curve x= t sin t, y=t cos t, 0<_ t <_1.
