Find the unit tangent vector T and the principal unit normal vector N. r(t) = (10t sin t + 10cos t)i + (10t cos t - 10 sin t)j - 10k
A. T = (-cos t)i - (sin t)j; N = (sin t)i + (cos t)j B. T = (cos t)i - (sin t)j; N = (-sin t)i - (cos t)j C. T = (-cos t)i - (sin t)j; N = (sin t)i - (cos t)j D. T = (cos t)i + (sin t)j; N = (-sin t)i + (cos t)j
