Question 133

Multiple Choice

Find parametric equations for the tangent line to the curve with the given parametric equations at the specified point. Select the correct answer.
x=cost,y=2e6t,z=2e6t;(1,2,2) x = \cos t , y = 2 e ^ { 6 t } , z = 2 e ^ { - 6 t } ; ( 1,2,2 )


A) x=t,y=224t,z=2+24tx = t , y = 2 - 24 t , z = 2 + 24 t
B) x=1,y=224t,z=424tx = 1 , y = 2 - 24 t , z = 4 - 24 t
C) x=1,y=2+12t,z=212tx = 1 , y = 2 + 12 t , z = 2 - 12 t
D) x=0,y=224t,z=2+24tx = 0 , y = 2 - 24 t , z = 2 + 24 t
E) x=t,y=2+12t,z=212tx = t , y = 2 + 12 t , z = 2 - 12 t
