Given theta = (19pi) / 6 how do you find tantheta? Trigonometry Right Triangles Trigonometric Functions of Any Angle 1 Answer Alan P. Jun 30, 2015 tan((19pi)/6) = 1/sqrt(3) Explanation: theta =(19 pi)/6 = 2pi + (pi+pi/6) So theta has a reference angle of pi/6 in quadrant 3. tan(theta) is positive in quadrant 3 and pi/6 is a standard angle with tan(pi/6) = 1/sqrt(3) Answer link Related questions How do you find the trigonometric functions of any angle?
