What are the sine cosine and tangent of theta=7pi/4 radians

FrozenT [24]

Answer:

see explanation

Step-by-step explanation:

$\frac{7\pi }{4}$ is in the fourth quadrant

Where sin and tan are < 0 , cos > 0

The related acute angle is 2π - $\frac{7\pi }{4}$ = $\frac{\pi }{4}$

Hence

sin([ $\frac{7\pi }{4}$ ) = - sin( $\frac{\pi }{4}$ ) = - $\frac{1}{\sqrt{2} }$ = - $\frac{\sqrt{2} }{2}$

cos( $\frac{7\pi }{4}$ ) = cos( $\frac{\pi }{4}$ ) = $\frac{\sqrt{2} }{2}$

tan( $\frac{7\pi }{4}$ = - tan( $\frac{\pi }{4}$ = - 1
