" (b) "sin{2cos^(-1)(-(3)/(5))}

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=

Evaluate: sin [2cos^(-1) ((-3)/(5))]

sin(2 cos^(-1). 3/5)=

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

If quad x_(1)=cos^(-1)((3)/(5))+cos^(-1)((2sqrt(2))/(3)) and x_(2)=sin^(-1)((3)/(5))+sin^(-1)((2sqrt(2))/(5))

Evaluate sin[2cos^(-1)(-3/5)] .
