Find T, N, and B for the Given Space Curve

question 88

Multiple Choice

Find T, N, and B for the given space curve.
-r(t) = (8t sin t + 8cos t) i + (8t cos t - 8 sin t) j - 5k

• A) T = (-cos t)i - (sin t)j; N = (sin t)i - (cos t)j; B = -5k
• B) T = (cos t)i + (sin t)j; N = (-sin t)i + (cos t)j; B = k
• 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
