Find sin(2*x*), cos(2*x*), and tan(2*x*) from the given information.

tan(*x*) = − 1/4 , cos(*x*) > 0

sin(2x)=

cos(2x)=

tan(2x)=

#### Top Answer

We have tan( x ) = − 1/4 , cos( x ) > 0; hence, x is in 4th quadrant. Hence, sin(x) =... View the full answer

- 3rd line : cosx= sqrt(1-sin2x)= sqrt(1-1/17)= 4/sqrt(17)
