Find the value of tan theta if sin theta = 12/13 and theta is in quadrant 2
nadya68 [22]

In quadrant 2, \sin\theta>0 and \cos\theta. Use the Pythagorean identity to establish that

\sin^2\theta+\cos^2\theta=1\implies\cos\theta=-\sqrt{1-\sin^2\theta}=-\dfrac5{13}

Then

\tan\theta=\dfrac{\sin\theta}{\cos\theta}=\dfrac{\frac{12}{13}}{-\frac5{13}}=-\dfrac{12}5
