Find T, N, and B for the given space curve.r(t) = (ln(cos t) + 2)i + 8j + (3 + t )k, -?/2 < t < ?/2
A. T = (sin t)i + (cos t)k; N = (cos t)i - (sin t)k; B = -j B. T = (sin t)i + (cos t)k; N = (cos t)i - (sin t)k; B = j C. T = (-sin t)i + (cos t)k; N = (-cos t)i - (sin t)k; B = -j D. T = (-sin t)i + (cos t)k; N = (-cos t)i - (sin t)k; B = j
