-$\left( \frac { \sqrt { 7 } } { 4 } , \frac { 3 } { 4 } \right)$
Find sect.
A) $\frac { \sqrt { 7 } } { 3 }$
B) $\frac { 3 \sqrt { 7 } } { 7 }$
C) $\frac { 4 } { 3 }$
D) $\frac { 4 \sqrt { 7 } } { 7 }$

Secant is the reciprocal of cosine, and since the x-coordinate represents the cosine of the angle in a unit circle, sec(t) = 1/cos(t) = 1/(sqrt(7)/4) = 4/sqrt(7), which simplifies to 4sqrt(7)/7 when rationalized.
