question 114

Multiple Choice

For the curve r(t) , find an equation for the indicated plane at the given value of t.
- $\left. \mathbf { r } ( \mathrm { t } ) = \left( 3 \sin \frac { 5 } { 3 } \mathrm { t } + 7 \right) \mathbf { i } + ( 3 \cos 20 \mathrm { t } ) - 6 \right) \mathbf { j } + 12 \mathrm { k } \mathbf { k }$ ; osculating plane at $t = 2.5 \pi$ .
