Find T, N, and B for the given space curve.r(t) = (5t sin t + 5cos t)i + (5t cos t - 5 sin t)j - 5k
A. T = (-cos t)i + (sin t)j; N = (sin t)i + (cos t)j; B = -k B. T = (-cos t)i - (sin t)j; N = sin(t)i - (cos t)j; B = 5k C. T = (-cos t)i - (sin t)j; N = (sin t)i - (cos t)j; B = k D. T = (-cos t)i - (sin t)j; N = (sin t)i - (cos t)j; B = -k
