Trigonometry problem.
show your solution and explain it. you

Cute one!

Summarizing:
sec(acot(tan(asin(sin(pi/3   use asin(sin(x))=x
=sec(acot(tan(pi/3)))
=sec(acot(sqrt(3)))   use acot(x)=atan(1/x)
=sec(atan(1/sqrt(3)))
=sec(atan(sqrt(3)/3))   evaluate atan(sqrt(3)/3), use unit circle
=sec(pi/6)
=1/cos(pi/6) evaluate cos(pi/6), use unit circle
=1/(sqrt(3)/2)  
=2/sqrt(3)   now rationalize
=2sqrt(3)/3

Iwish i knew the answer but i don’t but someone will come and us
