Question

find the value of square root 1 minus cos squared theta​

Answer 1

$= = > \: \: \sqrt{1 - \cos ^{2} \theta } \\ \\ = = > \: \: \sqrt{ \sin^{2} \theta } \qquad \quad \: ( \because \: \sin^{2} \theta + { \cos}^{2} \theta = 1 \: ) \\ \\ = = > \sin \theta$

Answer 2

Answer:

√1 - cos²∅

√sin²∅ {1 - cos²∅ = sin²∅}

sin∅
