Let `f(x)=cos(sqrt2 x) + cos(sqrt3x).` Consider the following statements

Let f(x)=((2sin x+sin2x)/(2cos x+sin2x)*(1-cos x)/(1-sin x));x in R Consider the following statements.

Let f(x)=sqrt((cos^(-1)sqrt(1-x^(2))-sin^(-1)x)) then which of the following statement/s is are correct -

Let f(x)=cos3x+sin sqrt(3)x. Then f(x) is

Let f(x)=sqrt(cos x). Then dom (f ) =?

Let f(x) = cos(x) + cos(sqrt(3)x) AA x in R . The number of values of x for which f(x) is maximum is

If f(x)=cos^(- 1)x+cos^(- 1){x/2+1/2sqrt(3-3x^2)} then

If f(x)=cos^(- 1)x+cos^(- 1){x/2+1/2sqrt(3-3x^2)} then

Solve sqrt2 (sin x +cos x) = sqrt3

f(x)=cos^(-1)(x^(2)/sqrt(1+x^(2)))
