Find the value of$$ \sqrt{cot^{2}\theta-cos^{2}\theta}$$?
$$ \sqrt{cot^{2}\theta-cos^{2}\theta}$$
$$ \sqrt{(cos^{2}\theta/sin^{2}\theta)-cos^{2}\theta}$$
$$ \cos^{2}\theta \sqrt{(1/sin^{2}\theta)-1}$$
$$ \cos^{2}\theta \sqrt{(1-sin^{2}\theta)sin^{2}\theta}$$
$$ \cos^{2}\theta \sqrt{cos^{2}\theta-sin^{2}\theta}$$
therefore, $$cot\theta$$ $$cos\theta$$
