Based on Pythagorean identities, which equation is true? sine squared theta minus 1 = cosine squared theta secant squared theta

Naddik [55]

Answer:

$Cot^2\theta-Csc^2\theta=-1$

Step-by-step explanation:

The only Pythagorean identities are:

$1. \ Sin^2\theta+Cos^2\theta=1$

$2. \ 1+Tan^2\theta=Sec^2\theta$

$3. \ 1+Cot^2\theta=Csc^2\theta$

$4. \ Sin^2\theta=1-Cos^2\theta\\ \ \ Cos^2\theta=1-Sin^2\theta$

Therefore, $Cot^2\theta-Csc^2\theta=-1$ is correct as it's one of the pythagorean identities.
