if secx=√2. and 3π<x<2π,find the value of 1+tanx+cosecx/1+cotx-cosecx
Answers
Hii..
secx=√2
x=45 degree
1+1+√2/1+1-√2
2+√2/2-√2
Answer:
-1
Step-by-step explanation:
From the question we know that x is lying in 4th quadrant..since 3π/2 < x < 2π where π=180 degree
we have sec x = √2..therefore..cos = 1/√2
Form formula-> sin²x = 1 - cos² x
we have_sin x = - 1/√2 ( minus because all value of trigonometry function are negative in forth quadrant except cos and sec )
Therefore cosec x = -√2 ( cosec x = 1/sinx )
now, tan x = -1 ( tan x = sin x / cos x)
and cot x = -1 too ( cot x = 1/tan x )
To find value of,
1 + tan x + cosec x
÷
1 + cot x - coesc x
Solution:-
= 1 - 1 - √2
÷
1 - 1- ( - √2)
= - √2
÷
√2
= -1 ( Answer )
