" 9."sin2x(tan x+cot x)=2

sin 2x (tan x + cot x) = ?

For 0 lt x lt (pi)/(2),(sin x )/(cos x )*( sec x)/("cosec" x)*( tan x)/(cot x )=9 . Then x=

If sin^(2) x tan x + cos ^(2) x cot x - sin 2 x = 1 + tan x + cot x x in (0, pi) then x =

int((cot x)/(sin x)-tan^(2)x-(tan x)/(cos x)+(2)/(cos^(2)x))dx

If tan x + cot x =2 , then sin^(2n)x + cos^(2n) x is equal to

If tan x + cot x =2 , then sin^(2n)x + cos^(2n) x is equal to

Solve : 2+tan x. cot\ (x)/(2)+cot x. tan\ (x)/(2)=0 .

(i) 4 cot x - 1/2 cos x + 2/cosx - 3/sin x + ( 6 cot x)/(cosecx) + 9 (ii) -5 tan x + 4 tan x cos x -3 cotx sec x + 2 sec x -13

tan^(2)2x + cot^(2)2x + 2tan 2x + 2 cot 2x=6

tan^(2)x+cot^(2)x=2
