" D58"quad sin((1)/(2)cos^(-1)((4)/(5)))

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

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

The value of sin((1)/(2)"cos"^(-1)(4)/(5)) is -

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

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

sin((1)/(2)cos^(-1).(4)/(5)) is equal to

If |z-25i|le15 , then |maximum arg(z) - minimum arg(z)| equals (A) (pi)/(2)+cos^(-1)((3)/(5)) (B) sin^(-1)((3)/(5))-cos^(-1)((3)/(5)) (C) 2cos^(-1)((4)/(5)) (D) 2cos^(-1)((1)/(5))

"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=
