Question

14. Prove that cos teta. cosec teta = cot teta​

Answer 1

Answer:

$l.h.s = \cos \theta \times cosec \theta \\ = \frac{ \cos \theta }{sin \theta} \\ = cot \theta \\ = \: r.h.s \\ \:$

Answer 2

$cos \theta.cosec \theta = cot \theta$

$cos \theta \: .1 \div sin \theta$

$cos \theta \: \div sin \theta \:$

$= cot \theta \:$
