Answer:
H) 2
Step-by-step explanation:
[tex]\frac {\sqrt {1 - \cos^{2}x}}{\sin x} + \frac {\sqrt {1 - \sin^{2}x}}{\cos x}[/tex]
= [tex]\frac {\sin x}{\sin x} + \frac {\cos x}{\cos x}[/tex] [since 0 < x < (π/2) and [tex]\sin^{2}x + \cos^{2}x = 1[/tex]]
= (1 + 1)
= 2
We know that in general,
by [tex]\sqrt {x}[/tex] we mean the positive square root of x only.
