Question

Evaluate the following :

$\frac{ \cos(45) }{ \sec(30) + \csc(30) ?}$


​

Answer 1

Answer:

As we know that the value of cos 45 is

$\frac{1}{ \sqrt{2} }$

as we know that value of sec 30 is

$\frac{2}{ \sqrt{3} }$

as we know that the value of cos 30 is

$\frac{ \sqrt{3} }{2}$

now do them properly like

$\frac{ \frac{1}{ \sqrt{2} } }{ \frac{2}{ \sqrt{3} } } + \frac{2}{ \sqrt{3} }$

On adding them we get certain answer

$\frac{1}{ \frac{2}{ \sqrt{3} } }$

Answer 2

Answer:

$\huge{\boxed{\boxed{\mathcal{Answer}}}}$

As we know that the value of cos 45 is

$\frac{1}{ \sqrt{2} }$

as we know that value of sec 30 is

$\frac{2}{ \sqrt{3} }$

as we know that the value of cos 30 is

$\frac{ \sqrt{3} }{2}$
