Question

$if \sin = \sqrt{} \frac{3}{5} then \: find \: value \: of \: \sqrt{ \sec ^2 } + \csc ^2$
answer it fast it important​

Answer 1

Step-by-step explanation:

$since \: sin(2x) = \sqrt \frac{3}{2}$

$but \: sin \: (60) = \sqrt \frac{3}{2}$

$therefore \: sin \: (2x) = sin \: (60)$

$or \: 2x = 60$

$or \:x = \frac{60}{2} = 30$

$therefore \: \sin(3x) = sin(3 \times 3)$

$= \sin(90) = 1$
