Multiple Choice

$\text { For the curve } r ( t ) \text {, write the acceleration in the form aTT } + \text { anN. }$
-r(t) = (t + 10) i + (ln(cos t) - 6) j + 2k

A) a = (sec t tan t) T + (sec t) N
B) a = (sec t tan t) T - (sec t) N
C) a = (-sec t tan t) T + (sec t) N
D) a = (-sec t tan t) T - (sec t) N
