`cos (sinx)`

Prove that : 2 tan 2x= (cos x+sinx)/(cos x-sinx)-(cos x- sinx)/(cos x+sinx) .

int(dx)/(cos x-sinx) is equal to

The period of f(x)=(1)/(2){(| sinx|)/(cos x)+(|cos|)/(sinx)} , is

tan^(-1)((cosx+sinx)/(cos x-sinx))

If f(x) = |{:(cos^(2)x, cosx.sinx, -sin x),(cos x sinx ,sin^(2)x ,cos x),(sinx , -cos x , 0):}| then for all x

If f(x) = |{:(cos^(2)x, cosx.sinx, -sin x),(cos x sinx ,sin^(2)x ,cos x),(sinx , -cos x , 0):}| then for all x

x sinx(dy)/(dx)+(x cos x+sinx)y=sinx

Solve the following differential equation: (sinx+cos x)dy+(cos x-sinx)dx=0

The number of integers in the range of the function f(x)=|4((sqrt(cos"x")-sqrt(sinx))(sqrt(cos"x")+sqrt(sinx)))/(cosx+sinx)| is______
