Question

if 1 - sin squared theta minus cos squared theta equals to ​

Answer 1

Step-by-step explanation:

= Cos²theta - Cos²theta ( as 1- sin²theta = Cos ² theta)

= 0

Answer 2

The value of $1-\sin^2 \theta-\cos^2 \theta$ is equal to "zero (0)".

Step-by-step explanation:

We have,

$1-\sin^2 \theta-\cos^2 \theta$

To find, the value of $1-\sin^2 \theta-\cos^2 \theta=?$

∴ $1-\sin^2 \theta-\cos^2 \theta$

Using the trigonometric identity,

$\sin^2 A+\cos^2 A=1$

⇒ $\cos^2 A=1-\sin^2 A$

$=\cos^2 \theta-\cos^2 \theta$

= 0

∴ The value of $1-\sin^2 \theta-\cos^2 \theta$ is equal to zero (0).

Hence, the value of $1-\sin^2 \theta-\cos^2 \theta$ is equal to "zero (0)".
