3.Trigonometrical Ratios, Functions and Identities
easy
यदि $\sin \theta = \frac{{24}}{{25}} $ हो और $\theta $ द्वितीय चतुर्थांश में है, तब $\sec \theta + \tan \theta = $
A
$-3$
B
$-5$
C
$-7$
D
$-9$
Solution
(c) $\sin \theta = \frac{{24}}{{25}} $
$\Rightarrow \cos \theta = \frac{{ – 7}}{{25}},\,\tan \theta = \frac{{ – 24}}{7}$
$\therefore$ $\sec \theta + \tan \theta = \frac{{ – 25}}{7} + \frac{{ – 24}}{7} = – 7$
