Question

1 + cos 2 theta divided by sin 2 theta ​

Answer 1

Answer:

here theta = x

$\frac{1 + \cos2x}{ \sin2x } \\ = \frac{2 { \cos }^{2}x }{2 \sin \: x \: \times \cos \: x } \\ = \frac{ \cos \: x}{ \sin \: x} \\ = \cot \: x$

Some formula which you should memorize:

$1 + cos2\theta = 2 cos^2\theta$

$1 - cos2\theta = 2 sin^2\theta$

$sin2\theta = 2 sin\theta cos\theta$

Friend , do you understand?

If yes give one thanks, so that I can understand.
