Question

if 1 + cos theta/ 1 - cos theta = 36/49 find cosec theta - sec theta/ cosec theta + sec theta​

Answer 1

Answer:

$- \frac{97}{71}$

Step-by-step explanation:

Using Adition subtraction method.....

$\sec(theta) = - \frac{85}{13}$

so.

$\cos(theta) = - \frac{13}{85}$

then....

$\sin(theta) = \frac{84}{85}$

and...

$\csc(theta) = \frac{85}{84}$

then putting those numbers....

$\frac{( \csc(theta) - \sec(theta) ) }{( \csc(theta) + \sec(theta) ) } = \frac{ \frac{85}{84} + \frac{85}{13} }{ \frac{85}{84} - \frac{85}{13} }$

Calculating the value.....

$\frac{( \csc(theta) - \sec(theta) ) }{( \csc(theta) + \sec(theta) ) } = - \frac{97}{71} </p><p>$

I am done .
