The value of $\frac{\sin^{2}30^\circ + \cos^{2} 60^\circ + \sec 45^\circ . \sin 45^\circ}{\sec 60^\circ + cosec 30^\circ}$ |
$ \frac{1}{4}$ $-\frac{3}{8}$ $\frac{3}{8}$ $-\frac{1}{4}$ |
$\frac{3}{8}$ |
\(\frac{sin²30º + cos²60º + sec45º . sin45º}{sec60º + cosec30º}\) = \(\frac{1/4 + 1/4 + 2/√2 }{ 2 + 2}\) = \(\frac{1/2 + 1 }{ 4}\) = \(\frac{3 }{ 8}\) |
