WARRIOR [948]

$\bf -3\sqrt{180}\qquad \begin{cases} 180=&2\cdot 2\cdot 3\cdot 3\cdot 5\\ &2^2\cdot 3^2\cdot 5\\ &(2\cdot 3)^2\cdot 5\\ &6^2\cdot 5 \end{cases}\implies -3\sqrt{6^2\cdot 5}\implies -18\sqrt{5}$

Find the length of l on the curve r(t)=5cos(3t)i-5sin(3t)j+3tk over the interval [3,7]

stealth61 [152]

$\mathbf r(t)=5\cos3t\,\mathbf i-5\sin3t\,\mathbf j+3t\,\mathbf k$
$\mathrm d\mathbf r(t)=\mathbf r'(t)\,\mathrm dt=(-15\sin3t\,\mathbf i-15\cos3t\,\mathbf j+3\,\mathbf k)\,\mathrm dt$

$\displaystyle\int_C\mathrm d\mathbf r(t)=\int_{t=3}^{t=7}\|\mathbf r'(t)\,\mathrm dt\|=\int_{t=3}^{t=7}\sqrt{225\sin^23t+225\cos^23t+9}\,\mathrm dt$
$=\displaystyle3\sqrt{26}\int_{t=3}^{t=7}\mathrm dt$
$=12\sqrt{26}$
