Question

If 8 tan N=15, Find the value of 1/√1-cos^2 N

Answer 1

Answer:

HERE'S YOUR ANSWER

• GIVEN: 8tanN=15
• =tanN=15/8 (tanN=P/B)

AND,

$\frac{1}{ \sqrt{1 - {cos}^{2} n} } = \frac{1}{ \sqrt{ {sin}^{2}n } } = \frac{1}{sinn} \\ = cosec$

now we know cosec²N-cot²N=1 (since tanN=15/8 =>cotN=8/15

=> cosec²N-(8/15)²=1

= cosec²N= 1- 64/225

=cosec²N= 161/225

=cosecN=(161)^1/2/ 15

Answer 2

${ {{ answer : cosecN=(161)^1/2/ 15 }}}$
