​

Answer 1

tan

(−17π4)

Add full rotations of 2π until the angle is between 0 and 2π.tan

(7π4)

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because tangent is negative in the fourth quadrant.

−tan(π4)

The exact value of

tan (π4) is 1.−1⋅1

Multiply −1 by 1.
