`Sec(x)+tan(x)=3" then "sin(x)=?`

If sin(x+4)^(@)sec(x-4)^(@)=1 then find tan((2x)/(3))=?

If y=(sin x)^(tan x), then (dy)/(dx)= (a) (sin x)^(tan x)(1+sec^(2)x log sin x)(b)tan x(sin x)^(tan x-1)cos x(c)(sin x)^(tan x)(d)sec^(2)x log sin x tan x(sin x)^(tan x-1)

Ify=( sec x^(@) +tan x^(@))/( sec ^(@) -tan x^(@) ) ,then (dy)/(dx)

If sin(x+y).sec(x-y)=1 then tan^(2)x+sin^(2)x+sec^(2)x=?

which one the following does not reduce to sin x for every x ,where defiened,is (A)(tan x)/(sec x)(B)(sin x)/(sec^(2)x-tan^(2)x) (C) (sin^(2)x sec x)/(tan x)

x=a sec^(3)theta tan theta,y=b tan^(3)theta sec theta then sin^(2)theta=

sec^(4)x-sec^(2)x=3 then find tan^(4)x+tan^(2)x

sin^-1(-x) = -sin^-1(x); cos^-1(-x) = pi - cos^-1(x); tan^-1(-x) = -tan^-1(x); cot^-1(-x) = pi - cot^-1(x); sec^-1(-x) = pi - sec^-1(x); cosec^-1(-x) = -cosec^-1(X)

Solve the following trigonometric equations, (i) "sin"x tan x-1="tan" x-"sin" x (ii) 4 cos x-3 sec x="tan" x (iii) cotx+tanx=2 cosec x.

If sec A+tan A=x then sec A=
