let `f(x)=e^(cos^(-1)sin(x + pi/3))` then `f((8pi)/9) and f((-7pi)/4)`

let f(x)=e^(cos-1)sin(x+(pi)/(3)) then f((8 pi)/(9)) and f((-7 pi)/(4))

Let f(x)=e^(cos^-1sin(x+pi/3)) , then

Let f(x)=e^(cos^(-1){sin(x+pi/3)}) Then, f((8pi)/9)= (a) e^(5pi//18) (b) e^(13pi//18) (c) e^(-2pi//18) (d) none of these

Let f(x)=e^cos^ (( -1 )) {sin(x+pi/3)}dot Then, f((8pi)/9)= e^(5pi//18) (b) e^(13pi//18) (c) e^(-2pi//18) (d) none of these

Let f(x)=e^cos^((-1)){sin(x+pi/3)}dot Then, f((8pi)/9)= e^(5pi//18) (b) e^(13pi//18) (c) e^(-2pi//18) (d) none of these

Let f(x)=e^(cos^(-1){sin(x+(pi)/(3))}) Then,f((8 pi)/(9))=(a)e^(5 pi/18)( b) e^(13 pi/18)(c)e^(-2 pi/18) (d) none of these

Let f(x) = x cos^(-1)(-sin|x|) , x in (-pi/2,pi/2)

Let f(x) = x cos^(-1)(sin-|x|) , x in (-pi/2,pi/2)

If f(x)=(1-sin^(2)x)/(1+sin^(2)x)," then "3f'((pi)/(4))-f((pi)/(4))=

If f(x)=|cos x-sin x|, find f'((pi)/(6)) and f'((pi)/(3))
