Answer:

2

Step-by-step explanation:

√(1 - cos^2x) = sin x

and

√(1 - sin^2x) = cos x

So the expression becomes:

sin x / sin x  + cos x / cos x

= 2

Answer:

H

Step-by-step explanation:

using the trigonometric identity

• sin²x + cos²x = 1

⇒ sinx = √(1 - cos²x) and cosx = √(1 - sin²x)

We can express as

[tex]\frac{sinx}{sinx}[/tex] + cosx / cosx = 1 + 1 = 2 → H
