Question

|Q4
If sinx+ cosec x=2 then value of sin’x + cosec'x (1m)
Q5
If sec x + tan x = 6 , then find sec x-tan x
(1m)​

Answer 1

Answer:

secx - tanx = 1/6

.........

Answer 2

Answer:

(sec x + tan x)(sec x -tan x) =sec^2 x -tan^2 x

We know sec^2 x -tan^2 x =1

Put the values in eqn.

2 * (sec x -tan x) = 1

sec x -tan x =1/2

*************************************************

I can't understand what's there meaning of '  in sin' x + cosec' x

if it's inverse then,

sin' x + cosec ' x = cosec x +sin x =2

Hope it helps :-)
