Possible Answers: Correct answer: Explanation: You can begin by imagining a little triangle in the second quadrant to find your reference angle. It would look like this: The tangent of an angle is: For our data, this is: Now, since this is in the second quadrant, the value is negative, given the periodic nature of the tangent function.tan (150) tan ( 150) 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 second quadrant. −tan(30) - tan ( 30) The exact value of tan(30) tan ( 30) is √3 3 3 3. − √3 3 - 3 3 The result can be shown in multiple forms. Exact Form:Transcript. Since tangent is not a one-to-one function, the domain must be limited to -pi/2 to pi/2, which is called the restricted tangent function. The graph of the inverse tangent function is a reflection of the restricted tangent function over y = x. Note that the vertical asymptotes become horizontal, at y = pi/2 and y = -pi/2, and the ... Example: Solve tan θ = −1.3. We get the first solution from the calculator = tan-1 (−1.3) = −52.4º. This is less than 0º, so we add 360º: −52.4º + 360º = 307.6º (Quadrant IV) The other solution is −52.4º + 180º = 127.6º (Quadrant II) tan(a) = -2 means that the angle "a" is in the second quadrant, QII, OR in the fourth quadrant, QIV. tan(a) = -2 means that the opposite leg of the right angled triangle has the length 2, while the adjacent leg is of the length 1. It implies that the hypotenuse is = units long, and therefore |sin(a)| = .
