Find the unit tangent vector T and the principal unit normal vector N. r(t) = (ln(cos t) + 4)i + 7j + (1 + t )k, -?/2 < t < ?/2
A. T = (-sin t)i + (cos t)k; N = (-cos t)i - (sin t)k B. T = (sin t)i - (cos t)k; N = (cos t)i - (sin t)k; C. T = (sin t)i + (cos t)k; N = (cos t)i - (sin t)k D. T = (-sin t)i + (cos t)k; N = (-cos t)i + (sin t)k
