Question

Find the quadrant in which $\theta$ lies, if
(i) $\cos \theta$ is negative but $\sin \theta$ is positve
(ii) $\sin \theta$ is negative but $\tan \theta$ is positive
(iii) $\cos \theta$ is negative and $\sin \theta$ is negative
(iv) $\cos \theta$ and $\cot \theta$ are both negative
(v) $\sec \theta$ is positive but $co\sec \theta$ is negative

Answer 1

From the basic knowledge of different quadrants and t-ratios we can easily say that the answers of the above five parts are (i) 2nd (ii) 3rd (iii) 3rd (iv) 2nd (v) 4th
