Answer 1

Question : if cos 0,sec 45,cosec 30,are in Gp then find common ratio​

Answer:

Common ratio = r = $\sqrt{2}$

Step-by-step explanation:

cos 0 , sec 45 , cosec 30 are in GP.

If a,b,c are in GP.

Then common ratio = b/a = c/b

Now cos 0 , sec 45 , cosec 30 are in GP.

So common ratio =  $\frac{sec 45}{cos0}$

=> common ratio =  $\frac{\sqrt{2} }{1} =\sqrt{2}$

and   $\frac{cosec 30}{sec 45}=\frac{2}{\sqrt{2} }=\sqrt{2}$
