sin((1)/(2)cos^(-1)((4)/(5)))

Find the value of sin(tan^(-1)((1)/(2))-cos^(-1)((4)/(5)))

Evaluate sin(1/2cos^(-1)(4/5))

Prove that: sin^(-1)((5)/(13))+cos^(-1)((4)/(5))=(1)/(2)sin^(-1)((3696)/(4225))

sin(cos^(-1)(4/5))

Prove that : sin^(-1)(5/13)+cos^(-1)(4/5)=1/2sin^(-1)(3696/4225) .

cos[2cos^(-1)((1)/(5))+sin^(-1)((1)/(5))] =

Which of the following angles is greater? theta_(1)=sin^(-1)((4)/(5))+sin^(-1)((1)/(3)) or theta_(2)=cos^(-1)((4)/(5))+cos^(-1)((1)/(3))

"Value of "sin(2sin^(-1)((4)/(5)))+sin(cos^(-1)((3)/(5)))=(a)/(b)quad (G.C.D of (a,b)=1) .Then a+b=

Evaluate cos(sin^(-1)(4/5)+cos^(-1)(2/3))
