`sin x + cos x=sqrt(2)`, then find `x`.

sin x+cos x=sqrt(2)sin5x

sin x + cos x = sqrt (2) cos A

If cos (pi/12) = (sqrt(2) + sqrt(6))/(4) , then all x in (0,pi/2) such that (sqrt(3)-1)/(sin x) + (sqrt(3)+1)/(cos x) = 4sqrt(2) , then find x.

cos x+sin x=sqrt(2)cos x then

If f(x)=cos^(-1)((1)/(sqrt(13)))(2cos x-3sin x)+sin^(-1)((1)/(sqrt(13)))(2cos x+3sin x)wdot rt sqrt(1+x^(2)) then find (df(x))/(dx) at x=(3)/(4)

If sin x + cos x = sqrt2 * c os x, "then : cos x - sin x = ...... A) sqrt2* cos x B) sqrt2* sin x C) sqrt2* (cos x +sinx) D)none of these

if: f(x)=(sin x)/(sqrt(1+tan^(2)x))-(cos x)/(sqrt(1+cot^(2)x)), then find the range of f(x)

If sin x+cos x=sqrt(2)cos alpha rArr x=
