## Step-by-step Solution

Problem to solve:

$\sin\left(x\right)^2+\cos\left(x\right)^2=1$

Choose the solving method

1

Applying the pythagorean identity: $\sin^2\left(\theta\right)+\cos^2\left(\theta\right)=1$

$1=1$
2

Since both sides of the equality are equal, we have proven the identity

true

true
$\sin\left(x\right)^2+\cos\left(x\right)^2=1$
