Question 93

Multiple Choice

One of sin x, cos x, and tan x is given. Find the other two if x lies in the specified interval.
- tanx=512,x\tan x = \frac { 5 } { 12 } , \quad x in [π,3π2]\left[ \pi , \frac { 3 \pi } { 2 } \right]


A) sinx=1213,cosx=513\sin x = \frac { 12 } { 13 } , \cos x = \frac { 5 } { 13 }
B) sinx=513,cosx=1213\sin x = - \frac { 5 } { 13 } , \cos x = - \frac { 12 } { 13 }
C) sinx=513,cosx=1213\sin x = \frac { 5 } { 13 } , \cos x = \frac { 12 } { 13 }
D) sinx=1213,cosx=513\sin x = - \frac { 12 } { 13 } , \cos x = - \frac { 5 } { 13 }
