`cosx+sinx=sqrt2 cosx` then

If cosx+sinx=sqrt2cosx and cosx-sinx=k.sinx, then k^2=?

If |[cosx, sinx, cosx], [-sinx, cosx, sinx], [-cosx, -sinx, cosx]|=0 , then x=

The most general solution of the equation sqrt3cosx +sinx = sqrt2 is :

The most general solution of the equation sqrt3cosx +sinx = sqrt2 is :

sinx + cosx = sqrt(2) cos2x

Solve the following equations: sinx+sqrt(2)=cosx

Solve: sinx+sqrt3cosx = sqrt2

If A=[{:(cosx,sinx),(-sinx,cosx)] then find |A|
