x = 7pi/4
When the angle is in standard position, which quadrant does the terminal side fall?
Find an angle coterminal with x.
Find the reference angle for x.
Find the exact value of tan(x)
7/4 pi is almost a full circle (2 pi) this angle is in Q IV
- pi/4 would be coterminal
reference pi/4
tan = sin / cos sin is negative in Q IV sin = - sqrt 2/ 2 cos = sqrt 2 /2 take it from here....
