Answer: The answer is 1.
Step-by-step explanation:
Here, the given expression is,
[tex]\frac{1-sin^2\theta}{cos^2\theta}[/tex]
[tex]=\frac{cos^2\theta}{cos^2\theta}[/tex]
( Because, sin² A + cos² A = 1 ⇒ cos² A = 1 - sin² A )
[tex]=1[/tex]
Hence, we can write,
[tex]\frac{1-sin^2\theta}{cos^2\theta}=1[/tex]
⇒ The answer is 1.
