Differentiate the functions given in Exercises 1 to 11 w.r.t. x. (x cos x)^(x)+ ( x sin x)^(1/x) .

The minimum value of sin x((1-cos x)/(sin x)+(sin x)/(1-cos x)) is

Maximum value of cos x((cos x)/(1-sin x)+(1-sin x)/(cos x))

The function f(x)=cos^(-1)((2[sin x|+|cos x|])/(sin^(2)x+2sin x+(11)/(4))) is defined if x belongs to (where [.] represents the greatest integer function)

(cos^(3) x- sin^(2) x)/(cos x - sin x)=(1)/(2) (2 + sin 2x)

Differentiate w.r.t.x the function in Exercises 1 to 11. (sin x- cos x)^( sin x - cos x), (pi)/(4) lt x lt (3pi)/(4) .
