`cos^(-1)(sin((pi)/(7)))`

(cos^(-1)(sin((7 pi)/6))

The principal values of cos^(-1)(-sin(7pi)/(6)) is

The value of sin^(-1)(sin((47 pi)/(7)))+cos^(-1)cos((60 pi)/(7))+tan^(-1)(-(tan)(29 pi)/(8))+cot^(-1)(cot(-(35 pi)/(8)))

If sin^(-1)(sin.(33pi)/(7))+cos^(-1)(cos.(46pi)/(7)) +tan^(-1)(-tan.(13pi)/(8))+cot^(-1)(-cot.(19pi)/(8))=(api)/(b) , where a and b are constant, then (a+b) is equal to

cos(cos^(-1)cos((8 pi)/(7))+tan^(-1)tan(8(pi)/(7))) has the value equal to -

cos^(-1)(cos((5 pi)/(3)))+sin^(-1)(sin((5 pi)/(3)))=
